The regions within a ferromagnetic material called domains are said to act like:
ASmall bar magnets
BTiny electric charges
CMiniature capacitors
DIndividual monopoles
Answer & Solution
Correct answer: A. Small bar magnets
1. Domains explain how a whole piece of iron becomes magnetic.
2. Ferromagnetic materials contain magnetic domains that are themselves magnets.
3. The regions within the material called domains act like small bar magnets.
4. Aligning them makes the whole object magnetic.
