Draw diagrams and explain how an emf is produced in a square wire loop if a uniform magnetic field is coming straight up from the floor, the square loop starts parallel to the floor, then the side closest to you rotates downward, stops, then upward.

Expert Solution

whenever the loop stops moving,the induced emf becomes zero because the wire doesn't experiences any change in field.the flemings right hand rule is applied by placing the three fingers perpendicular to each other.the emf is induced only in effective lenght of wire that is the side AB and CD the other parts BC and AD doesn't have any induduced emf because they moment of those parts is always parallel with the field direction.in the above given solution anly AB part is explained the similar phenomenon occurs in CD part of wire also.the solution is given considering the loop is rotating with respect to the center of axis shown in the figure.
