Problem 29.4: Rank currents in a loop

Please wait for the animation to completely load.

A loop, next to a very long current-carrying wire, moves along the path shown (position is given in meters and time is given in seconds). The trail of the loop is marked. The current in the wire is constant and is directed upward as shown by the arrow. Restart.

  1. For t = 0.5 s, 1.5 s, 2.5 s, 3.5 s, and 4.5 s, is the induced current in the loop clockwise, counterclockwise, or zero?
  2. Rank the magnitudes of the currents induced in the loop (smallest to greatest, explicitly indicating any ties) at t = 0.5 s, 1.5 s, 2.5 s, and 3.5 s.
