A coil is located at the center of a long solenoid of R= 15 cm whichhas 5x10^7 turns per meter and carries a current I=16 A. The coil is coaxial with the solenoid and consist of 5 turns of wire, each in shape of length a=5cm on each side.
What is the magnectic flux passing through each loop of the coil?
If the current in the solenoid is not constant but varies as I=Im cos(wt), where Im =16A and w= 10 rads/sec find the peak emf in the coil
