At tinitial the circular metal ring starts being squeezed until it becomes an ellipse by tfinal while keeping the same perimeter (there is no rotation). After that, the ring stays in the shape of an ellipse. Which of the following graphs below best represents the current through the ring E over time?

The B-field lines point straight upwards. The dashed parts of the loop are behind the screen and the solid parts of the loop are in front of the screen. E The normal to the loop is parallel to the external B-field lines initially. The external magnetic field has a magnitude of 0.5 T and the area of the loop is 0.25 m2. The loop is then rotated by 250 1 around the axis shown in 1.5 s.
