A circular copper disc of 10 cm radius rotates at `20 pi` `radian//sec` about an axis through its centre and perdendicular to the disc. A uniform magnetic field of 0.2 T acts perpendicular to the disc. Calculate the potential difference developed between axis of the disc and the rim. What is the induced current if resistance of disc is 2 ohm ?
