QPages 285-286: Q5: HC Verma: Concepts of Physics - Volume 2 Magnetic Properties of Matter Pages 285-286: Q5 Solution: The magnetic susceptibility is negative for ___________.

⚠️ Common Exam Traps & Conceptual Pitfalls

Students frequently mistake paramagnetic or ferromagnetic materials for having negative susceptibility, confusing ‘weak magnetism’ with sign; however susceptibility $chi = M/H$ is negative only when the induced magnetization opposes the applied field, which occurs exclusively for diamagnetic substances (paramagnetic and ferromagnetic always give $chi>0$).

The magnetic susceptibility is negative for ___________.

Multiple Choice Options

  • A paramagnetic materials only
  • B diamagnetic materials only
  • C ferromagnetic materials only
  • D paramagnetic and ferromagnetic materials

Step-by-Step Verified Solution

**Answer:** (b) diamagnetic materials only. **Step-by-Step Explanation:** Diamagnetic materials have negative susceptibility.
