The loop moves at a constant 10 cm/s. Plot a graph of the current in the loop

Question:

The loop moves at a constant 10 cm/s. Plot a graph of the current in the loop as a function of time. Label the axes with numerical values and take counterclockwise current to be positive.

In Fig. 20.4, a square metal loop of side 4.0 cm and resistance 5.0 Ω moves to the right (+x-direction) into, through, and out of a 6.0 cm wide region of uniform magnetic field perpendicular to the plane of the loop. The magnetic field in the region is 0.25 T. At t = 0, the loop just begins to enter the region of magnetic field.
