Four loops of conductive wire are exposed to magnetic fields that are perpendicular to the loops, In the images below, magnetic field lines. In each case, determine whether the induced current in the loop will be dockwise o counter-clockwise, as viewed the direction and behavior of each magnetic field is indicated by the behavior of the from above.

A circular wire loop of radius r = 11 cm is immersed in a uniform magnetic field B = 0.645 T with its plane normal to the direction of the field. If the field magnitude then decreases at a constant rate of −1.5×10−2 T/s , at what rate should r increase so that the induced emf within the loop is zero? Express your answer using two significant figures. The answer is not 0.00128
An elastic conducting material is stretched into a circular loop of 12.4 cm radius. It is placed with its plane perpendicular to a uniform 0.979 T magnetic field. When released, the radius of the loop starts to shrink at an instantaneous rate of 84.8 cm/s. What emf is induced in volts in the loop at that instant?
