Physics 201- Introduction to Electricity & Magnetism
December 2- Induced Magnetic Fields and Maxwell's Equations






  Induced electric fields/ emfs/ currents

For each of the following systems, state if there is a current through the resistor.  If there is a current, give its direction.

The switch in the left circuit is closed.


The left circuit moves to the left.


Both circuits move to the right at the same velocity


The loop in the right circuit compressed.


Using what you now know about indcued currents, speculate on how metal detectors function.
