    Fr. Kooi-
     I stand by what I said. A *strip* of copper will not be dampened by a 
    magnetic field. A *coil* of copper, wound like a coil in a motor, becomes 
    subject to induced voltages when a changing magnetic field is present. But 
    those voltages do not flow, and there is no resulting motion, unless there is 
    some type of closed coil or other circuit.
     A simple strip of copper, as per the orginal description, should be 
    unaffected by a nearby magnet. Try holding  piece of copper next to a 
    magnet--there is no attraction, no motion, no dampening. The results with a 
    helical coil will be the same. The results only change when a circuit is 
    established (i.e. a closed motor coil) so that the electricity may flow in 
    it.
     Perhaps I'm focusing too tightly on the term "strip", but I don't think any 
    simple strip of copper will be dampened by a magnetic field.
