Question ⤵

what are magnetic keepers ?

Answer ⤵

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,

Short definition ⤵

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.

Types ⤵

The three types of magnets are temporary, permanent, and electromagnets. Magnets are categorized by their source of magnetism. Temporary magnets become magnetized in the presence of a magnetic field
