You now hold the magnet still inside the coil. The galvanometer shows:
AReverse kick
BNo deflection
CSteady deflection
DFaster swings
Answer & Solution
Correct answer: B. No deflection
1. A still magnet means the flux is not changing.
2. No change in flux means no induced current.
3. The needle shows no deflection.
