Magnetic Flux1


No insulator for magnetic flux has yet been discovered. If a non-magnetic material is placed in a magnetic field, there is no appreciable change in flux—that is, the flux penetrates the non-magnetic material. For example, a glass plate placed between the poles of a horseshoe magnet will have no appreciable effect on its field, although glass itself is a good insulator in an electric circuit.
