A coil of wire having 40.0 turn of radius 3.0 cm is located between the poles of electromagnet that generates magnetic field directed to the north. The field rises from 0 to 0.75 T at a constant rate in a time interval of 225 s.
Determine the magnitude and direction of the induced current in the coil when the coil consists of 1 ohm resistance and the field is perpendicular to the plane of the coil?
