alleryA galvanometer shows no deflection when the magnet is held:
ASpinning fast
BStationary
CMoving in
DMoving out
Answer & Solution
Correct answer: B. Stationary
1. Deflection appears while the magnet approaches or recedes.
2. A still magnet gives no change of flux.
3. So a stationary magnet gives no deflection.
