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?
- AT : Large retentivity, small coercivity
- BP : Large retentivity, large coercivity
- CP : Small retentivity, large coercivity
- DT : Large retentivity, large coercivity
✓ Correct answer: B
