a single circular loop with radius of 10.0cm lies in the plane of the paper while a uniform magnetic field points out of the paper. If the magnitude of the magnetic field changes from 0.30 to 0.80 Tesla in 0.50 seconds:
a) what is the magnitude of the average induced emf?
b) if the coil resistance is 3 ohms, what is the average induced current?
c) What is the direction of the induced current in the loop?(clockwise or counter clockwise)
