Question

What is magnetic induction? State four ways of magnetizing an iron piece.​

Answer 1

Answer:

$\huge\red{Answer}$

Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction.

Explanation:

Solution:

Magnetic induction method.

We take a long iron nail and test it for magnetic properties by bringing near the magnetic substances. As we observe, nails don't attract magnetic substances. Now we bring a pole if a bar magnet near the head of the nail. Then we bring the iron paper clips near the pointed end of the nail and observe that the iron paper clips now get attracted towards the nail, this happens because iron nail becomes a magnet. Then we take the bar magnet away from the iron nail, paper clips fall off. This magnetism is temporary.

Single touch method.

We take a demagnetised piece of iron and place it on the surface of the table. Then we take a magnet and take one of the poles and rub it with the selected pole on the iron in one direction several times. Then after some time, the iron piece will turn into a magnet.
