A cylindrical bar magnet is rotated about its axis. A wire is
connected from the axis and is made to touch the cylindrical
surface through a 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 = 2π/⍵
(d) a time varying non-sinusoidal current flows through
the ammeter A.

Answer:

(b) no current flows through the ammeter A

Explanation:

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.
