ABSTRACT
Magnetic fields are typically conceptualized with so-called “flux lines” or “lines of force.” When such flux lines encounter any sort of matter, an interaction takes place in which the number of flux lines is either increased or decreased. The original magnetic field therefore becomes amplified or diminished in the body of matter as a result of the interaction. This is true whether the matter is a typical “magnetic” material, such as iron or nickel, or a so-called “nonmagnetic” material, such as copper or air.
