[Solved] The best material to make permanent magnets is [1]

Magnet: It is defined as a material that can produce its own magnetic field. Permanent magnet: These magnets do not lose their magnetic property once they are magnetized
– The alloy which are permanent magnets that are primarily made up of a combination of aluminium, nickel and cobalt but can also include copper, iron and titanium.. – It can be easily magnetized in an external magnetic field.
When exposed to permanent magnets, paramagnetic materials are weakly attracted.. – Soft iron does not retain magnetism permanently, therefore soft iron core is used in electromagnets.

Which of the following is used to make permanent magnets?A) Soft ironB) SteelC) NichromeD) Copper [2]

Which of the following is used to make permanent magnets?. Hint: More the ferromagnetic nature of an element the better its magnetic nature
This is due to the alignment pattern of their atoms being in the same direction.. Out of all the metals mentioned in the question the most ferromagnetic material is steel
From the remaining three materials in the question, steel can stay as a magnet for the longest time even after removing it from a magnetic field. This makes steel the best material to make permanent magnets.

Solenoid can be used for making permanent magnets. Explain how this is done ? [3]

A permanent magnet can be demagnetised using current. Alnico is used for making permanent magnets because it has

What are permanent magnets? What is an efficient way of preparing a permanent magnet? Write two characteristic properties of materials which are required to select them for making permanent magnets. [4]

What are permanent magnets? What is an efficient way of preparing a permanent magnet? Write two characteristic properties of materials which are required to select them for making permanent magnets.. Hint: Magnets are a type of materials which tend to have magnetizing properties
Here, we will understand about permanent magnets, their method of preparation and the properties of metal which are required to be a magnetic material.. Magnets are generally of two types namely permanent magnets and electromagnets.
Their magnetic property does not lose with time hence are known as permanent.. In order to make a permanent magnet efficiently, we have to put a ferromagnetic material inside a solenoid and pass electric currents through it

How to Make Your Own Permanent Magnets [5]

The non-homogeneous mix of magnetite, iron, oxygen and other trace elements in lodestone, the only naturally occurring magnet, is what makes it permanent (hard). Pure homogeneous magnetite or iron is not permanent but a temporary (soft) magnet
These alloys have elements with atoms that can be induced to point persistently in the same direction (ferromagnetic) making them strongly magnetic. Only three–iron, cobalt and nickel–of the 100 elements in the periodic table are ferromagnetic at room temperature
Use tongs to heat the steel nail over a stove, allowing atoms in the nail to move around more freely.. Use the compass to determine the Earth’s magnetic north and south poles

Magnet Manufacturing Process [6]

There are several processes for making magnets, but the most common method is called Powder Metallurgy. In this process, a suitable composition is pulverized into fine powder, compacted and heated to cause densification via “liquid phase sintering”
Ferrite, Samarium Cobalt (SmCo) and neodymium-iron-boron (neo) magnets are all made by this method. Unlike ferrite, which is a ceramic material, all of the rare earth magnets are metal alloys.
The molten alloy is either poured into a mold, onto a chill plate, or processed in a strip caster – a device that forms a thin, continuous metal strip. These cured metal “chunks” are crushed and pulverized to form a fine powder ranging from 3 to 7 microns in diameter

Manufacturing Processes for Permanent Magnets: Part I—Sintering and Casting [7]

Permanent magnets (PMs) produce magnetic fields and maintain the field even in the presence of an opposing magnetic field. Electrical machines using permanent magnets are more efficient than those without
RE elements such as Nd and Dy have become critical materials due to the growing demand and constrained supply. Improving the manufacturing process is effective in mitigating the RE criticality issue by reducing waste and improving parts consistency
The importance of RE elements is discussed along with their economic importance to green energy. The conventional sintering and casting manufacturing processes for commercial magnets, including Nd-Fe-B, Sm-Co, Alnico, and ferrite, are described in detail.

A new way to create permanent magnets [8]

Permanent magnets are widely used in industry, playing a particularly important role in power generators and motors. The best magnets are made of rare-earth metals, but as their name suggests, these elements are not ubiquitous in nature.
The most popular, so far, is an alloy called tetrataenite, made of an equal amount of iron and nickel arranged in a specific three-dimensional tetragonal pattern.. In nature, the formation of this atomic structure requires very specific conditions; namely, an extremely slow cooling of the alloy, which results in a change in the relative position of the atoms within the material’s crystal lattice
While traveling through space, these materials cool at a rate of a few degrees over million years as cooling occurs very slowly for a body (such as a meteor) that is already quite cold.. Even if this cooling rate could be achieved in a lab, it would be completely impractical for the industrial production of magnets

How exactly do you make a magnet? [9]

How Exactly Do You Make A Magnet? Here Is How They Are Made!. Magnets are some of the most interesting objects ever made in the world
Along with the intriguing topic of how magnets work, there is still the question of how they are made. As a result, I did all of the research to come up with the answers.
In general, there are 3 main types of magnets: permanent, temporary, and electromagnet. The materials that they are made of vary from rare-earth elements all the way to insulated wire.

High-Quality Permanent Magnets [12]

Permanent magnets are vital for many modern everyday appliances. You are never far from a permanent magnet, you are likely to have one in front of you right now, or if you are reading this article on a smartphone, you might even have one in your hand!
A permanent magnet is called a permanent magnet because its magnetism is ‘always on’, it generates its own persistent magnetic field unlike an electromagnet which is made from a coil of wire wrapped around a ferrous core and requires an electric current to generate a magnetic field.. An electromagnet’s magnetism can be controlled and turned off and on at the flick of a switch as the magnetism depends on a constant flow of electricity.
Some metals are defined as ferromagnetic, this means that they exhibit their own magnetic properties and are defined as magnetically ‘soft’ materials.. Permanent (hard) magnets and temporary (soft) magnets are both ferromagnetic but temporary magnets only display noticeable magnetic properties when influenced by a permanent magnet and tend to not stay magnetised.

Wikipedia [13]

A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc
An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic)
Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field, by one of several other types of magnetism.. Ferromagnetic materials can be divided into magnetically “soft” materials like annealed iron, which can be magnetized but do not tend to stay magnetized, and magnetically “hard” materials, which do

Magnetizing and Unmagnetizing [14]

A magnet is a material with poles and a magnetic field created by the configuration of its electrons. It must contain one of the three naturally magnetic metals, iron, nickel, and cobalt
When two opposite poles are brought together, they will attract. But when the same poles are nearby their fields will repel each other.
They cannot be turned off, nor can their fields be increased or decreased easily. There are a few ways to remove a magnetic field from a permanent magnet

How to Make Super Strong Permanent Magnets [15]

All the possible ways to make a permanent magnet are listed in Joseph Henry’s student notebook, which is kept at Princeton University. Henry, the 18th century American physicist, is known – together with Michael Faraday – as the father of electrical technology, so it’s no surprise that one of the methods he describes uses electricity
How strong? Definitely stronger than a fridge magnet.. Magnetism and electricity are not only related, they are two sides of the same coin, and it was the phenomenon of electromagnetic inductance, discovered independently by Henry and Faraday, that led to this realization
It’s possible to induce the electrons inside certain metals to spin in the same direction, and that gives the metal magnetic properties. The list of metals that do this isn’t long, but iron is one of them and, because steel is made from iron, it can also be magnetized.

Making a Magnet [16]

Magnets are made by exposing ferromagnetic metals like iron and nickel to magnetic fields.. There are three methods of making magnets: (1) Single touch method (2) Double touch method (3) Using electric current.
magnet that does not have a very big field of attraction. All you need is a ferromagnetic object and a permanent magnet.
Then rub the permanent magnet over the surface of the object. It is also necessary to lift the magnet from the surface of the object, after every swipe or run

Process for making permanent magnets and products thereof [17]

SThis invention relates to a process for making permanent magnets.. Permanent magnets are made of iron alloys with high carbon content and greater or smaller additions of chromium, cobalt, copper and so forth
These difficulties of working and shaping are increased by the circumstance that the steels must be hardened before magnetising because only by hardening do they acquire the requisite properties for permanent magnets. In this hardened condition, final working which is often necessary because 0 of the distortion and changes of form resulting from the hardening process, can only be effected by grinding
Much greater difficulties as regards working 5 are met with owing to their great hardness and crystalline structure, in the case of nickel-aluminium steel alloys whose coercive force is above 240 gauss (oersted). These magnet steels in any case can only be cast in bar form, so that for 0 use in apparatus separate soft iron limbs or pole shoes must be attached to the magnets

Permanent Magnets [18]

I’ve covered how to make a temporary magnet, but what if you want a magnet that won’t lose its properties. After I found that article on what my temporary magnetization technique was called (stroking), I was interested in trying to make the permanent magnet ( http://en.wikipedia.org/wiki/Magnets – Under: Magnetization of materials).
Unfortunately it really was quite weak, so I tried to increase the magnetic field and it worked much better.. Two metal electrical boxes (Don’t ask me what each one is called, just look at the pictures)
Large Magnet (This is needed for the stronger magnet, I used my 6×8 speaker magnet). Look at my paint drawing to get a general idea of the setup needed

Ceramic Magnets: Types, Uses, Features and Benefits [19]

An Alnico magnet is a permanent magnet made by combiming aluminum, nickel, iron, cobalt, and other elements. They come in isotropic, non-directional, or anisotropic, mono-directional, form…
This article takes an in depth look at ceramic magnets and their use.. A ceramic magnet, also known as a ferrite magnet, is a permanent magnet made by combining iron oxide and strontium carbonate
Ceramic magnets are a low cost replacement for natural magnets and are found in everyday devices and industrial applications. They are the most widely used type of magnets in the world, found in 75% of all products that require a magnet

Permanent Magnet – Joseph Henry Project [20]

Lay a piece of iron on the table and put the north pole in the middle and draw it over half the iron, than put the south pole on and draw it over the other half. Take two magnets put one North pole and one South pole on the middle of the iron
Take a steel bar, hold it vertically, and strike the end several times with a hammer, and it will become a permanent magnet.. Take the horse shoe magnet, place it in the middle of the needle to be magnetized and draw it over one half of the needle an equal number of times
Take a small bar of steel magnetize it by percussion, and then magnetize several small bars. Put them in a bundle with their North poles the same way and we will have a magnet for making others with.”
