Question

A wire loop of resistance 10ohm
and radius 10 cm is kept in the plane of this
paper in a uniform magnetic field B. The direction of B is perpendicular to the
plane of the page and points out of it and its magnitude is increasing at the rate
of 0.50 Ts-Determine the magnitude and direction of the induced current in the
loop.
b) What rate of change of current in a solenoid having self-inductance 19.4 mH
produces a self-induced emf of 100 mV in it?​
