Question

What is magnetic induction? What type of magnets can be made by this method- temporary or permanent?

Answer 1

1. Magnet: A substance that has the property of attracting iron, steel, cobalt, and nickel.
2. The phenomenon by which an ordinary piece of iron acquires magnetic properties temporarily, due to the presence of another magnet near it, is called magnetic induction.
3. Induced magnetism is a temporary process.
4. If the permanent magnet is removed, the magnetic material will usually lose its induced magnetism.
5. So, the temporary magnets can be only made via magnetic induction.
