A magnet is brought towards a coil
What will be the induced e.m.f./induced charge respectively?
Induced Electromotive Force:
When the magnet is bought speedily:
When the magnet is bought speedily near the coil, the rate of change of flux will increase. So, the induced e.m.f will be higher in this case. However since the induced charge is independent of time, it will not be affected.
Induced Charge:
When the magnet is bought slowly:
When the magnet is bought slowly the induced charge will remain the same, as it does not depend on time while the rate of change of flux will be lower.
Hence,
