Answer:
(b) heat it for some time
Explanation:
You can heat a magnet to the Curie point. ... The energy we have applied to the magnetic poles will make the magnet point in different directions, so the poles will be deformed. It is also possible to demagnetize a magnet by hitting the ends of the magnet with a hammer, which will alter the order of the magnet.
Note : Heating a magnet doesn't completely demagnetize the magnet, but only reduces its magnetic power.
