A planar wire loop is placed perpendicular to uniform magnetic field . Wire loop starts rotating in its own plane about its axis with uniform angular velocity omega . If B is magnetic field intensity then what will be the induced emf in the loop ?

A uniform circular loop of radius a and resistance R is pulled at a constant velocity v out of a region of a uniform plane of the loop and the velocity are both perpendicular to B. Then the electrical power in the circular loop at the instant when the arc (of the circular loop) outside the region of magnetic field subtends an angle (pi)/(3) at the centre of the loop is

A very small circular loop of radius a is initially coplanar & concentric with a much larger circular loop of radius b (gtgta) . A constant current is passed in the large loop which is kept fixed in space & the small loop is rotated with angular velocity omega about a diameter. The resistance of the small loop is R & its self inductance is negligible. The current in the larger loop is clockwise. Calculate how much torque must be exerted on the small loop to rotate it.
