Coercivity and retentivity of soft iron is

Options

  1. Ahigh coercivity, high retentivity
  2. Blow coercivity, high retentivity
  3. Clow coercivity, low retentivity
  4. Dhigh coercivity, low retentivity

Correct answer

C. low coercivity, low retentivity

Step-by-step solution

Coercivity and retentivity of soft iron is low, because its magnetisation disappears easily on the removal of external magnetising field.
