alleryCurrent can be induced in a coil by moving it in a field or by:
ACooling the magnet
BCutting the wire
CChanging the field
DCharging the coil
Answer & Solution
Correct answer: C. Changing the field
1. There are two practical ways to bring about the change.
2. The coil can be moved in a magnetic field, or the field around it can be changed.
3. Moving the coil is usually the more convenient one.
