A circular disc of 10cm radius rotates at 20pie rad/sec about an axis through its centre and perpendicular to the disc. A uniform magnetic field of 0.2 T acts perpendicular to the disc.

i) calculate the potential diff. developed between the axis of the disc and the rim.

ii) what is the induced current if the resistance of the disc is 2 ohm?
