A rectangular coil with resistance R has N turns, each of length l and width w. The coil moves into a uniform magnetic field B with constant velocity v.
What are the magnitude and direction of the total magnetic force on the coil as it enters the magnetic field.
What are the magnitude and direction of the total magnetic force on the coil as it moves within the field.
What are the magnitude and direction of the total magnetic force on the coil as it leaves the field?
