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.
