QUESTION #1 Motional EMF
A uniform magnetic field of 0.4 mathrmT acts perpendicular to a circular copper disc 20 mathrm~cm in radius. The disc is having a uniform angular velocity of 10 pi rad mathrms^-1 about an axis through its centre and perpendicular to the disc. What is the potential difference developed between the axis of the disc and the rim? ( pi = 3.14 )
