  • In a dipole magnetic field, and it looks like the Earth???s magnetic field, a charged particle will move in a circle around the magnetic field line, but if it has also some motion northward, say, it will spiral toward the north pole, and then because of the converging magnetic field and other forces, it will spiral back and forth as it goes around.
