Question

A circuit consists of a circular loop of wire with a radius a=28.3×10^-2 m. the circuit has a resistor with a resistance R1 = 9.1 . the circuit is entirely immersed a uniform magnetic filed whose magnitude changes over time . if the rate of change of the magnetic field is either decreasing or increasimg with 3.7 T/s

a)find the current induced in the circuit. write your answer in mA and to 2 decimal places

b) indicate the direction of the current in your answers as follows - clockwise or + counter clockwise
