Angle of Attack

[TinselKoala]

If I am understanding you correctly, the polarity of the induced voltage will reverse when either the direction of motion or the polarity of the field lines (magnet pole) is reversed. If you reverse them both you wind up with the same polarity you started with.

This link has a really good explanation of the effects of relative motion/angle/direction of field and conductor:

Thanks TinselKoala, that helped a lot.

   If an electron is sitting still or at rest RELAVANT to the observer there flows from the electron to the observer virtual particles that tells the observer the electron is negatively charged.  When the electron moves there flows from the electron to the observer ACCELERATED virtual particles that tells the observer the electron is moving.  The accelerated virtual particles form CURRENTS between the observer and the MOVING electron.  As an electron moves further and further away from the observer the observer begins to see less and less of the intrinsic virtual particle flow of the electron until at some point the communication line snaps.  They call this magnetic reconnection.  This is when the flow of virtual particles between the observer and the electron drops below the scalar virtual particle flow and the observer magnetically reconnects with the ambient currents.  This magnetic reconnection is often observed as a transient or spike of great amplitude and very short wavelength.  It is used in the flyback transformers in a television to charge the tube to 30,000 volts between anode and cathode.  When the diode between the flyback transformer and the anode becomes shorted the high voltage developed across the tube discharges back through the flyback transformer where the secondary of the flyback becomes the primary and the resulting current pulse in the secondary pops the horizontal output transistor which is driving the primary.  The same magnetic reconnection was used in automobile ignition systems.  The flyback is used to charge the spark plug gap.  This magnetic reconnection event occurs very regularly on Earth as the little electron we are taking a ride on stresses the electrostatic field generated by the Sun.  The efield snaps and the Earth magnetically reconnects with the scalar current flows.
