Question

You are given two identical bars
which look as if they might be
made of iron. One of them is a
magnet, while the other is a
simple iron bar. How will
you find out, which one
is a magnet?​

Answer 1

Answer:

Take a magnet, and take it near both the ends of both bars, with the north pole.

Explanation:

In case of the iron bar, both sides will be attracted by any of the poles of the magnet.

In case of the magnet bar, one of the sides will be repelled from the north pole, and other from the south pole of the magnet.
