Question

Steel is used for making ____ magnets.
A. electromagnet
B. permanent
C. right angles
D. anti-clockwise

Answer 1

Hint:Here first we will see how many types of magnets are there then we will understand each of the types of magnet and then we will distinguish among the given options which fits the best for steel and why and then answer the given question.

Complete answer:
An object capable of generating a magnetic field and attracting unlike poles while repelling like poles is referred to as a magnet. There are three types of magnets, and they are as follows:
-Permanent magnet
-Temporary magnet
-Electromagnets.

Permanent magnets: Permanent magnets are the most widely used magnets. They're called permanent magnets because once magnetised, they don't lose their magnetic properties.
The methods for demagnetizing permanent magnets are as follows:
-Magnets are subjected to high temperatures.
-When a magnet is pounded, the magnetic interaction between the atoms weakens.
-The magnetic power of one magnet will be reduced if it is struck with the other in an ineffective manner.
There are four types of permanent magnets:
-Ceramic or ferrite
-Alnico
-Samarium Cobalt (SmCo)
-Neodymium Iron Boron (NIB)

Temporary Magnet: In the presence of a magnetic field, temporary magnets may be magnetised. These materials lose their magnetic properties when the magnetic field is removed. Temporary magnets include things like iron nails and paper clips.

Electromagnets: An electromagnet is made up of a coil of wire wrapped around an iron heart. As this material is exposed to an electric current, it generates a magnetic field, which causes it to behave like a magnet. Controlling the electric current will change the strength of the magnetic field.

When a nonmagnetic piece of steel is placed near a magnet, the atoms inside it rearrange in such a way that a permanent magnet is created. As the atoms align, a magnetic field is created that maintains its power. The atoms of an object must be correctly positioned in order to generate a magnetic field. Because of the natural placement of its atoms, steel is extremely successful.

Therefore, option B is the correct answer.

Note:Permanent magnets are made from a variety of materials, including steel. Ceramic, copper, cobalt, nickel, gadolinium, and neodymium are all used to make permanent magnets. Iron, on the other hand, is a much more affordable and readily available commodity than the aforementioned materials. For these reasons, many permanent magnet manufacturers choose to use steel in their designs
