A metallic ring with the area of 10^-4m^2 is pierced with a magnetic field of 1 Tesla perpendicular to the area. During the time of t=10^-4 seconds the ring is pulled to the right magnetic field drops to zero. You can assume that during this time of t=10s the ring has moved a distance of 10^-1m where there is no flux.
a) What is the induced emf in the ring during this time of t=10^-4s.
b) If the ring has a resistance of 1 ohm what will be the power dissipated in the ring?
c) What will be the force needed to move the ring the distance of 10^-1n where the magnetic field is zero.?
