A copper disc of radius 1m is rotated about its natural axis with an angular velocity 2 "rad"//"sec" in a uniform magnetic field 5 telsa with its plane perpendicular to the field. Find the emf induced between the centre of the disc and its rim.

A copper disc of radius 1 m is rotated about its natural axis with an angular velocity 2 rad/sec in a uniform magnetic field of 5 tesla with its plane perpendicular to the field. Find the emf induced between the centre of the disc and its rim.

A copper disc of radius Im is rotated about its natural axis with an angular velocity 2 rad/sec in a uniform magnetic field of 5 tesla with its plane perpendicular to the field. Find the emf induced between the centre of the disc and its rim.
