Question

Why are magnetic keepers used to store magnets. ​

Answer 1

Explanation:

• A magnet keeper, also known historically as an armature, is a bar made from magnetically soft iron or steel, which is placed across the poles of a permanent magnet to help preserve the strength of the magnet by completing the magnetic circuit; it is important for magnets that have low magnetic coercivity,

Answer 2

Answer:

• A magnetic keeper is a piece of wood or soft iron which is used in storing magnets because bar magnets get demagnetised when the poles are left free for a long time.
• In order to preserve the magnetism of the magnets, a keeper is kept across a pair of bar magnets with unlike poles beside each other.
