1. A coil is lee aced at the center of a long solenoid of radius R = 15 cm which has 5 x 107 turnis per meter and carries a current 1=16 A. The coil is coaxial with the solenoid and consist of 5 turns of wire, each in shape of a square of length a=Scm on each side.
A. What is the magnetic flux passing through each loop of the coil?
B. If the current in the solenoid is not constant but varies as I = Im cos ωt , where Im =16 A and ω =10 rad/sec, find the pake mf induced in the coil.
