Question

(a) Explain how a strong permanent magnet can be made. (b) Suggest a method to make a temporary magnet. ​

Answer 1

Answer:

Take two magnets and combine them. On the centre of the iron, place one North pole and one South pole.

There are three different ways to make magnets: single touch, double touch, and electric current.

Explanation:

• Permanent magnets are constructed of "hard" ferromagnetic materials like alnico and ferrite, which are subjected to specific processing in a strong magnetic field during production to align their internal microcrystalline structure, making them extremely difficult to demagnetize.
• By stroking a piece of iron or steel (such as a needle) along a permanent magnet, you may produce a temporary magnet. An electromagnet is a method of creating a temporary magnet that employs electricity. Let's get started!
