A cylindrical bar magnet is rotated about its axis as shown in figure. A wire is connected from the axis and is made to touch Bar the cylindrical surface through a ma 8 net contact. Then
A
A direct current flows in the ammeter A.
B
No current flows through the ammeter A.
C
An alternating sinusoidal current flows through the ammeter A with a time period, T = 
D
A time varying non-sinusoidal current flows through the ammeter A.
Text Solution
Verified by ExpertsThe correct answer is:
NOT AVAILABLE
As there is no change in magnetic flux associated with the circuit no current is induced in the circuit the ammeter A shows no deflection.
