Problem 4) Induced current in a wire loop [40 points] A square wire loop of side length 10 cm has resistance R=200 2 and lies in a horizontal plane. A uniform magnetic field B points vertically downward (into the plane), and in 0.1 s it increases linearly from 10 mT to 30 mT. a) Find the magnetic flux @,; through the loop at the beginning of the 0.1-s period. b) Find the magnetic flux PB, f through the loop at the end of the 0.1-s period. c) Find the loop current / during the 0.1-s period. d) What is the direction of the loop current
