Magnetic Materials & Curie Law

A soft ferromagnetic material is placed in an external magnetic field. The magnetic domains:

Show answer and solution

Answer: (a)

  1. In a field, domains aligned with the field grow and others shrink (domain wall motion).
  2. In stronger fields the domain magnetization also rotates towards the field.
  3. So domains may increase or decrease in size and change orientation: the answer is (a).
