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…
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…
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,…
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…
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…
Doubled Tuned Coupled Circuits: Figure 10.24 shows a Doubled Tuned Coupled Circuits involving two series resonant circuits. For the circuit shown in the figure, a special case where the primary and secondary resonate at the…
Single Tuned Circuit: Consider the Single Tuned Circuit in Fig. 10.21. A tank circuit (i.e. a parallel resonant circuit) on the secondary side is inductively coupled to coil (1) which is excited by a source,…
Parallel Connection of Coupled Coils: Parallel Connection of Coupled Coils - Consider two inductors with self inductances L1 and L2 connected parallel which are mutually coupled with mutual inductance M as shown in Fig. 10.20.…
