In an unmagnetised ferromagnet, the domains are:
APerfectly aligned
BCompletely absent
CElectrically charg
DRandomly oriented
Answer & Solution
Correct answer: D. Randomly oriented
1. Each domain is magnetised on its own.
2. Their directions cancel out across the sample.
3. So the domains are randomly oriented.
4. The answer is randomly oriented.
