Problem 2) Induced current in a wire loop [50 points] A square wire loop of side length 5 cm has resistance R = 1002 and lies in a horizontal plane. A uniform magnetic field B points vertically upward (out of the page), and in 1.0 seconds it decreases linearly from 30 mT to 10 mT. a) Find the magnetic flux B,i through the loop at the beginning of the 1.0-s period. b) Find the magnetic flux O, B,f through the loop at the end of the 1.0-s period. c) Find the loop current I during the 1.0-s period. d) What is the direction of the loop current I? Justify your answer.
