22.1: Magnetic Flux, Induction, and Faraday's Law
Induced EMF. The apparatus used by Faraday to demonstrate that magnetic fields can create currents is illustrated in the following figure. When the switch is closed, a magnetic field is produced in the coil on the top part of the iron ring and transmitted (or guided) to the coil on the bottom part of the ring.

Some old and new concepts in magnetic separation
Magnetic fields, or regions of a magnetic field have been termed isodynamic, katadynamic or anadynamic. Force constant in magnitude throughout an isodynamic field region has proved useful in concentrating particles according to slight differences in magnetic susceptibilities. In the kata-dynamic field region the highest gradients of …

The isodynamic vibrator at the upper end of the chute was replaced by an asymmetric vibrator, as described by Faul and Davis (1959).
Magnetic Separation
Diamagnetic minerals – These minerals are repelled by a magnetic field; hence they can be separated from a mixture by the passing of a magnetic field; The most commonly used magnetic separator is the Frantz Isodynamic Magnetic Separator. It consists of a large electromagnet, through which mineral mixtures are passed on a metal trough.
