A Loop with a Resistance of 4

Multiple Choice

A loop with a resistance of 4.0 is pushed to the left at a constant speed of 2.0 m/s by a 24 N force.At the instant shown in the figure,the loop is partially in and partially out of a uniform magnetic field.An induced current flows from left to right through the resistor.The length and width of the loop are 2.0 m and 1.0 m,respectively.

-Determine the magnitude of the uniform magnetic field.

A) 2.2 T
B) 3.5 T
C) 6.4 T
D) 7.0 T
E) 9.1 T
