I know that magnetic fields create moving charges (an electric current) normal to the plane of the magnetic force lines. I also have heard that magnetic and electric fields create each other in a perpendicular direction to the other (badly worded). Electric currents are moving charges (usually electrons), but electric fields are propagated through lines of force, not in one direction. How are these equivalent? Also, if there are no charges in the area of the magnetic field (it is emitted from a ferromagnetic substance), then how does the magnetic field create moving charges? I know that oscillating magnetic and electric fields is basically what EM radiation is. However, I cannot visualize light (a transverse wave with a finite amplitude, frequency and wavelength which travels in a single direction) as two fields that turn into each other rapidly. If that were true, then EM waves would be projected in all directions in a sphere from the source. If a photon is equivalent to a standing wave probability function, and photons move in a single direction, how does this make sense (as these two things are equivalent, but seem different)?
