Question

(d)
197. It is learnt that all magnetic substances loss their
magnetism when :
(a) Placed in water
(6) Heated
(c) Brought near a magnetic field
(d) In winter​

Answer 1

Answer:

if magnets are heated they lose their magnetism. Placing them in a magnetic field won't make them lose their magnetism however if two like poles are stored together that is if a north pole is on top of a north pole this will cause the magnet to weaken...therefore its wise to store north and south poles together.
