⚠️ Common Exam Traps & Conceptual Pitfalls

Students often mix up retentivity and coercivity, choosing high retentivity with low coercive force because it seems easier to magnetise. Remember that permanent (hard) magnets need both high retentivity *and* high coercive force to retain magnetisation and resist demagnetisation, unlike soft magnetic materials which have low coercivity.

The desirable properties for making permanent magnets are _________________.

Multiple Choice Options

  • A high retentivity and high coercive force
  • B high retentivity and low coercive force
  • C low retentivity and high coercive force
  • D low retentivity and low coercive force

Step-by-Step Verified Solution

**Answer:** (a) high retentivity and high coercive force. **Step-by-Step Explanation:** Permanent magnets need high retentivity (to retain magnetisation) and high coercive force (to resist demagnetisation).
