Exploration 29.3: Loop Near a Wire

Please wait for the animation to completely load.

A loop is near a wire that has a current flowing upward.  You can drag the loop (position is given in meters, magnetic field strength is given in millitesla, emf is given in millivolts, and time is given in seconds).  The flux through the loop and the induced emf are shown in the graph.  The animation will stop after 30 s.  Restart.  

  1. How do the emf and the flux through the loop change as you drag the loop toward and away from the wire?

  2. How do the emf and the flux through the loop change as you drag the loop parallel to the wire?

  3. Are the flux and emf different when the loop is on the left side, instead of the right side, of the current-carrying wire?  Explain.
