## Parallel Magnetic Circuit

Parallel Magnetic Circuit: We have seen that a series magnetic circuit carries the same flux and the total mmf required to produce a given quantity of flux is the sum of the mmf’ s for the separate parts. In a Parallel Magnetic Circuit, different parts of the circuit are in parallel. For such circuits the […]

## Magnetic Leakage and Fringing

Magnetic Leakage and Fringing: Magnetic Leakage and Fringing – Figure 10.28 shows a magnetized iron ring with a narrow air gap, and the flux which crosses the gap can be regarded as useful flux. Some of the total flux produced by the ring does not cross the air gap, but instead takes a shorter route […]

## Difference Between Electric Circuit and Magnetic Circuit

Difference Between Electric Circuit and Magnetic Circuit: A Difference Between Electric Circuit and Magnetic Circuit are shown in Figs. 10.27(a) and (b) respectively. Figure 10.27(a) represents an electric circuit with three resistances connected in series, the dc source E drives the current I through all the three resistances whose voltage drops are V1,V2 and V3. Hence, […]

## Series Magnetic Circuit

Series Magnetic Circuit: A series magnetic circuit is analogous to a series electric circuit. Kirchhoff s laws are applicable to magnetic circuits also. Consider a ring specimen having a magnetic path of l meters, area of cross-section (A)m2 with a mean radius of R meters having a coil of N turns carrying I amperes wound […]

## Magnetic Circuit Analysis

Magnetic Circuit Analysis: Magnetic Circuit Analysis – The presence of charges in space or in a medium creates an electric field, similarly the flow of current in a conductor sets up a magnetic field. Electric field is represented by electric flux lines, magnetic flux lines are used to describe the magnetic field. The path of […]
