inductive coupling
inductive coupling
(OP)
Hello everyone,
I'm not sure how to discribe this but I'll do my best.
What I would like to do is induce a current in a closed loop circuit using a permanent magnet. The closed loop has a wire running through it which is independent of the closed loop. The wire then is formed into a coil and runs back through the closed loop attaching itself to the original wire, in effect another closed loop. If the coil is wound in a counter-clockwise direction and then in another setup all-together, wind the coil in a clockwise direction would the polarity be the opposite relative to each other?
Thanks

RE: inductive coupling
Where is the magnet in relation to the coils and what is the relative motion of the magnet in relation to the coils.
It is possible that the polarity of something may be reversed, but as I visualize your description, any induced voltages in the second coil will cancel each other for a net result of zero volts. Polarity is meaningless for a zero quantity, but the induced voltages will have reversed their polarity before they cancel. (+X volts)+(-X volts)=0 and (-X volts)+(+X volts)=0
However, as I visualize your setup, the wires of the second coil may be parallel to the magnetic field. If so, there will be no cutting of magnetic flux and no voltage(s) induced.
