I have seen the movement of a current carrying conductor in a magnetic field attributed to two different causes. 1) Interaction of the conductor's magnetic field with the magnetic field its in 2) Interaction of the conductor's moving charges with the magnetic field its in My question is related to conducting an experiment to demonstrate whether 1 is the attributable cause by testing the hypothesis of 1. I can envision building a permanent magnet mimicing a current carrying conductor by magnetizing long angular slices (i.e. angular sections of a long cylinder) of permanent magnet material by inserting them into a similarly shaped gap in the bend of a magnetic circuit which is as wide as the cylinder slices are long. These angular slices would then be combining to make a cylindrical permanent magnet with a circular magnetic field. However, I'm unsure whether the nature of the resulting manetic field would mimic that of a current carrying conductor which has been described in the literature as increasing linearly from zero at the conductor's center to a maximum at the conductor's surface and then decreasing inversely as the square of the distance from the conductor's surface in the space outside the conductor. Your thoughts/suggestions are appreciated.
