A ferromagnet is divided internally into regions called:
ALattices
BSectors
CDomains
DCircuits
Answer & Solution
Correct answer: C. Domains
1. Each region has its own net magnetisation.
2. They point in different directions when unmagnetised.
3. These regions are called domains.
4. So the answer is domains.
