A square loop moves at a constant velocity of 1 m/s to the right across two regions of uniform magnetic field. One region extends from x = -4 to x = 0, and has a uniform field directed into the page. The second region extends from x = 0 to x = 4, with a uniform magnetic field directed out of the page. The magnitudes of the fields are equal.
Plot the magnetic flux through the loop, and the induced current, as a function of time. Take the flux to be positive if the field is into the page, and take clockwise to be positive for induced current.
