The animation shows the top view of a four wire conducing loop and a galvanometer. Current flowing into the + terminal, i.e., counterclockwise in the loop, will deflect the meter to the right. Plot the magnetic field passing through the loop during the time interval t=0 to t=10. Assume the field is zero at t=0. Start.
Drag the wire on the right hand side to a new position. How does this change the galvanometer reading?
