Select the incorrect alternative (s): When a ferromagnetic material goes through a complete cycle of magnetization, the magnetic susceptibility:
Text Solution
Verified by ExpertsThe correct answer is:
A
Step 1: Understand magnetic susceptibility in ferromagnetic materials. Magnetic susceptibility ($\chi$) is a measure of how much a material will become magnetized in an applied magnetic field.
Step 2: In ferromagnetic materials, susceptibility can vary during the magnetization cycle due to hysteresis effects.
Step 3: Analyze the options:
Step 2: In ferromagnetic materials, susceptibility can vary during the magnetization cycle due to hysteresis effects.
Step 3: Analyze the options:
- Option A: has a fixed value - This is incorrect because magnetic susceptibility in ferromagnetic materials changes as the material goes through magnetization and demagnetization cycles.
- Option B: may be zero - This can occur when the material is above its Curie temperature.
- Option C: may be infinite - This can occur when a material becomes fully magnetized and reaches saturation.
- Option D: None of these - Since option A is incorrect, this option is also incorrect.
