A rectangular coil with 50 turns of wire and a resistance of 2.0 ohms is laying flat on the desk in front of you as shown in the figure. The rectangular coil has dimensions of
40cm\times 25cm. Initially there is a uniform magnetic field of 0.80 T pointing downward through the coil. The magnetic field then changes to a uniform 0.10 T field pointing downwards in a time of 3.0 s . a. What is the magnitude and direction of the average induced current in the coil during those 3.0 seconds?
