alleryTo get a bigger induced emf from the same flux change, you should:
AUse fewer turns
BCool the coil
CPaint the coil
DAdd more turns
Answer & Solution
Correct answer: D. Add more turns
1. Each turn of the coil feels the same flux change.
2. The emfs of all turns add up.
3. More turns give a bigger emf.
