In the figure a square loop is shown, which is inside a uniform magnetic field of magnitude 0.400 T that is pointing out of the page. Initially both sides of the loop are equal to 20.0 cm. Both sides of the loop start to increase at t = 0 at an equal constant rate of 6.00 cm /s until t = 20.0 s. %3D a) Find the magnitude of the emf induced in the loop at t = 15.0 s. b) What is the direction of the induced current at t = 15.0 s and why? c) Find the induced emf in the loop at t = 30.0 s. %3D
