O clockwise O counterclockwise O no current Submit My Answers Give Up

Explanation / Answer

Area of loop A = (pi*D2)/4 = 0.025383 m2.

Part A) EMF induced is E = A*(dB/dt) = (0.025383)*0.5 = 0.014176 Volts.

Part B) Induced Current I = E/R = 0.014176/0.9 = 0.01575 Amperes.

Part C) The direction of current is Clockwise.
