Adiabatic invariance The properties of magnetic mirrors can be derived using the adiabatic invariance of magnetic flux under changes in magnetic field strength.
Both of these EMF's, despite their different origins, can be described by the same equation, namely, the EMF is the rate of change of magnetic flux through the wire.
Because of their symmetry, toroidal cores allow a minimum of the magnetic flux to escape outside the core (called leakage flux ), so they radiate less electromagnetic interference than other shapes.
By adding a " magnetic core " made of a ferromagnetic material like iron inside the coil, the magnetizing field from the coil will induce magnetization in the material, increasing the magnetic flux.
By contrast, when the circuit is in the phantom configuration the currents in the two wires of each pair are in the same direction and the magnetic flux is being cancelled.
As the magnet moves with respect to the coil, the magnetic flux linkage of the coil changes.
