A rectangular loop moves at the speed vo to the right in the figure next to it. Assume that the loop has the total resistance R. The motion is such that it passes through an area with a constant B-field with the strength B_0 which is directed upwards / outwards from the plane of the paper / screen. Outside of this area, the B field is zero. The dimensions of the loop and in the area with a B-field is shown by the figure.

a) Calculate how the induced voltage in the rectangular loop depends on its motion over the area with the B-field. Expression induced stress as a function of the position of the loop.

b) The induced voltage causes a current to circulate in the loop. Determine its amount and direction of the different positions of the loop.

c)During the movement of the loop through the area with B-field, it is affected by a force. How big is this force and what direction is it pointing?
