Chapter: Electrical machines : Magnetic Circuits and Magnetic Materials

Flux Linkage, Inductance and Energy

A coil wound on a magnetic core, is used frequently used in electric circuits.

Flux Linkage, Inductance and Energy

1. Flux Linkage

When flux is changing with time and relative motion between the coils flux exist between both the coils or conductors and emf induces in both coil and the total induced emf e is given as

2. Inductance and Energy

A coil wound on a magnetic core, is used frequently used in electric circuits. The coil may be representsd by an ideal circuit element called inductance which is defined as the flux linkage of the coil per ampere of its circuit
