The Figure shows a rectangular loop with a=4.6 cm, and b=3.1 cm, moving with a velocity v=6.2 cm/s into an area where the magnetic field is uniform, pointing into the page, and whose magnitude is B= 440 mT.
1) What is in volts the induced emf in the loop when the loop is moving in a region where the magnetic field is uniform?
2) We stop the instead and loop, while keeping it at the region of uniform field, we pull two opposite ends of the loop apart until the overall area of the loop is zero. If it takes 0.14 seconds to do that, what is in volts the induced emf in the loop?
3) What is the direction of the induced current then? Clockwise counter clockwise
