Moving Conducting Rod in Magnetic Field.avi

Check out the details of moving a metal rod through a magnetic field. A magnetic force
qv x B polarizes the rod. But then the rod polarizes, and there is also a voltage difference and electric field the opposite direction. Those forces will eventually balance, qE = qvB. In the end the voltage difference across the rod will be our Faraday's law result for moving loops, emf = -Blv.

I would like to add that a rod does not need to be moving in order for the rod to become a dipole. I understand that one would need to move the rod into the B-field and or vise versa and perhaps this is where the dipole is setup in the rod. Once the rod is in the B-field and not moving it remains a magnet, once you remove it from the B-field, it becomes unmagnetized.

This was a very good, and clear lesson. Thanks a lot.
