When a ferromagnetic material goes through a hysteresis loop, the magnetic susceptibility

Multiple Choice Options

  • A has a fixed value
  • B may be zero
  • C may be infinity
  • D may be negative

Step-by-Step Verified Solution

**Answer:** (c) may be infinity. **Step-by-Step Explanation:** At the steepest part of the hysteresis loop, the susceptibility dM/dH may be very large (approaching infinity for an ideal ferromagnet).
