6. Mike Faraday folds 4 meters of copper wire (cross-section10-7 m2) into a square and holds it in a uniform magnetic field ofstrength 2.0 Tesla. The field passes directly through the“circuit”—pointing towards Mike’s face as he looks down at hissquare. a) Over what time interval should Mike’s assistant crank upthe field to 5.0 Tesla if Mike hopes to achieve a current of 0.5 A?b) Will Mike observe a clockwise current or a counterclockwisecurrent?
