Magnetic Circuits Pdf To formalise our problem solving capabilities, we will convert every conceivable electromagnetic device into an equivalent magnetic circuit and an equivalent electric circuit. Definition: the series magnetic circuit is defined as the magnetic circuit having a number of parts of different dimensions and materials carrying the same magnetic field.
Magnetic Circuits Pdf Inductance Inductor Kirchhoff ’s magnetomotive force law (kml) : in a closed magnetic circuit, the algebraic sum of the product of the magnetic field strength and the length of each part of the circuit is equal to the resultant magnetomotive force. The flow of magnetic flux induced in the ferromagnetic core can be made analogous to an electrical circuit, as shown in fig. 15, hence the name magnetic circuit is used. The magnetic circuit differs from the electric circuit in this respect; resistance is normally independent of current in an electric circuit, whereas reluctance depends on the flux density in the magnetic circuit.

Compute the flux through the magnetic circuit and the flux density in the i core. Flux lines leave the north seeking end of a magnet and enter the south seeking end. when placed in a magnetic field, a compass indicates north in the direction of the flux lines. Using a magnetic circuit, we can calculate inductance or mutual inductance (for a pair of coils). the concept of reluctance allows us to easily solve more complicated magnetic circuit problems. the magnetic flux does not change as we go through the air gap (so magnetic current is continuous). each segment of the structure is a reluctance.
