Current Loop I
A square loop of wire is rotating around its vertical axis in a magnetic field of strength B = 0.06 T as shown in View A. The angular frequency of rotation is
= 50 rad/s and the loop has a resistance of R = 5 
. The length of one side of the square loop is W = 0.05 m. At the instant of timewhen the normal to the loop makes an angle of 
= 30
with respect to the B field, as shown in View B where 'N' represents the normal,calculate the current flowing in the loop. Note: View A would be the side view if = 90 or 270.

A small square loop of wire carrying some current is located between the poles of a horseshoe mag- net as shown in the diagram. Throughout this problem you may assume that the magnetic field between the poles is constant. Note that the loop is shown skewed only to pro- vide some perspective. When the loop is vertical, its face is actually parallel to the poles of...
