A circular conducting loop with a radius of 0.1 m is placed

A circular conducting loop with a radius of 0.1 m is placed in a uniform magnetic field of 0.5 T. The magnetic field is changing at a rate of 0.02 Ts. The loop has a total resistance of 5 Q. (a) Calculate the induced electromotive force (e.m.f.) in the conducting loop due to the changing magnetic field. (b) Determine the magnitude of the current induced in the loop. (1 mark) (1 mark) (c) Calculate the power dissipated in the loop due to this induced current. (1 mark) (d) If the loop is part of a larger circuit and a 10 Q2 resistor is connected in series with it, calculate the total resistance of the circuit and the current flowing through it. (2 mark)
