When a magnet is pushed in and out of a ...

When a magnet is pushed in and out of a circular coil C connected to a very sensitive galvanometer G as shown in the adjoining diagram with a frequency v, then

A

Constant deflection is observed in the galvanometer

B

Visible small oscillations will be observed in the galvanometer if v is about 50 Hz

C

Oscillations in the deflection will be observed clearly if v = 1 or 2 Hz

D

No variation in the deflection will be seen if v = 1 or 2 Hz

Text Solution

Verified by Experts

The correct Answer is:
C
If frequency (f) is high then no deflection observed and at low frequency of 1 to 2Hz, oscillations may be observed as our eyes will be able to detect it.
