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?
Option: 1 T: Large retentivity, small coercivity
Option: 2 P: small retentivity, Large coercivity
Option: 3 T: Large retentivity, Large coercivity
Option: 4 P: Large retentivity, Large coercivity
Materials suitable for permanent magnets should have high retentivity, high coercivity, and high permeability.
