Case Study :
When a piece of unmagnetised magnetic
material touches or is brought near the pole of a
permanent magnet, it becomes a magnet itself or
we can say magnetism is induced. A north pole
induces a north pole in the far end and vice versa.
The induced magnetism is quickly lost when the
magnet is removed from the magnetic field.
Which of these statements about magnetic induction is correct?
A Induced magnetism always make permanent magnets.
B Magnetic induction explains why an unmagnetised material may be attracted by a magnet.
C A material must touch the magnet to be induced.
D Magnetism can be induced in all the materials.
I didn't get the question and it's answer.
