A single-turn circular loop of wire of radius 5.0 cm lies in the plane perpendicular to a spatially uniform magnetic field. During a 0.12-s time interval, the magnitude of the field increases uniformly from 0.2 T to 0.4 T. (a) Determine the electric potential induced in the loop. (b) If the magnetic field is pointing due north, find the direction of the induced current in the loop. 


2.) A coil of wire with 1 loop has a radius of 10 cm. The induced current in the wire is 125 mA when the magnetic field is pointing at an angle of 45° with the plane of the loop. If the magnetic field starts at 0 T and increases to 0.75 T in a time interval of 1.2 ms, find the resistance of the wire
