Each problem is worth 20 points. You must show your work in a logical fashion starting with the correctly applied physical principles which are on the last page. Your score will be maximized if your work is easy to follow because partial credit will be awarded. 1. The square loop shown at the right has a current of 10.0A and its plane is parallel with a 2.00T magnetic field. Its sides are 10.0cm long. (a)Find the magnitude and indicate the direction of the force on each side of the loop. (b)Describe the resulting motion of the loop assuming that it is released from rest from the position shown. 2. Find the magnitude and direction of the magnetic field at the center of the coil shown at the right. The coil has 100 turns, a radius of 5.00cm and carries 1.00A of current. I
