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 \[\nu \], then

A.            Constant deflection is observed in the galvanometer
B.            Visible small oscillations will be observed in the galvanometer if \[\nu \]is about 50 Hz
C.            Oscillations in the deflection will be observed clearly if \[\nu =1\] or 2 Hz
D.            No variation in the deflection will be seen if \[\nu =1\]or 2 Hz
Answer» D.            No variation in the deflection will be seen if \[\nu =1\]or 2 Hz
