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?

  1. T : Large retentivity, small coercivity
  2. P : small  retentivity, large coercivity
  3. T : Large retentivity, large coercivity
  4. P: large retentivity, large coercivity

Solution

As per the properties of Magnetic substances, materials favorable for permanent magnets should have high retentivity, large coercivity and high permeability.
