A Single Rectangular Wire Loop with a Height of 24 $\varOmega$

A single rectangular wire loop with a height of 24.0 cm and a width of 10.0 cm is mounted flat on an office door.The resistance of the loop is 3.85 $\varOmega$ .The Earth's magnetic field of 2.6 * 10^-5 T is uniform and perpendicular to the surface of the closed door.The door is then opened at a constant rate of 4.6 rad/s.Calculate the magnitude of the induced current 0.434 s after the door begins opening.

A) 4.7 * 10^-6 A
B) 4.1 * 10^-7 A
C) 1.1 * 10^-7 A
D) 1.3 * 10^-6 A
E) 6.8 * 10^-7 A
