Question:
Magnetic materials used for making permanent magnets (P) and magnets in a transformer (T) have different properties of the following, which property best matches for the type of magnet required?
Correct Option: , 4
Solution:
(4) Permanent magnets $(P)$ are made of materials with large retentivity and large coercivity. Transformer cores $(T)$ are made of materials with low retentivity and low coercivity.
