The emf Blv produced by a moving conductor is called:
AConstant emf
BReversed emf
CStanding emf
DMotional emf
Answer & Solution
Correct answer: D. Motional emf
1. A rod sliding on rails sweeps out area.
2. The flux through the circuit therefore changes.
3. The emf Blv so produced is called motional emf.
4. So the answer is motional emf.
