Spleta) Electric charges in motion are the sources of magnetic forces. b) Magnetic poles in motion are the only source of magnetic forces. c) Stationary electrons are the source of magnetic forces. d) Spinning protons are the source of all magnetic forces. a) Electric charges in motion are the sources of magnetic forces. SpletAt Earth’s surface, the magnetic field forms two poles (a dipole). The north and south magnetic poles have opposite positive and negative polarities, like a bar magnet. The … SpletAt Earth’s surface, the magnetic field forms two poles (a dipole). The north and south magnetic poles have opposite positive and negative polarities, like a bar magnet. The invisible lines of the magnetic field travel in a closed, continuous loop, flowing into Earth at the north magnetic pole and out at the south magnetic pole. seger and the silver bullet band
