Real Beads On Virtual Strings: Charged Particles On Magnetic Field Lines
Abstract
We discuss a similarity between the drift of a charged particle inside a slowly moving solenoid and the motion of a fluid element in an ideal incompressible fluid. This similarity can serve as a useful instructional example to illustrate the concepts of magnetic field lines and magnetic confinement. (C) 2012 American Association of Physics Teachers.
