A changing magnetic field inducing current in another conductor is called:
AElectromagnetic saturation
BElectromagnetic induction
CElectromagnetic attraction
DElectromagnetic separation
Answer & Solution
Correct answer: B. Electromagnetic induction
1. Current in the primary coil changes the magnetic field around it.
2. The changing field lines around the secondary coil induce a current in it.
3. This process is called electromagnetic induction.
