Magnetic coupling occurs, when there is no physical connection between two coils (or inductors). This coupling can be of either aiding type or opposing type. It is based on whether the current enters at the dotted terminal or leaves from the dotted terminal. Coupling of Aiding type

3.1 Theory of two magnetically coupled RLC circuits Two inductively coupled RLC circuits are shown below (Figure 1). Two resonant frequencies are obtained owing to the fact that there are two circuits. The separation of the two frequencies depends on the value of the mutual inductance M, defined as the ratio of the

The circuits studied so far can be considered as conductively coupled, since loops affect each other by current conduction. When two loops with or without contact affect each other through magnetic fields, they are said to be magnetically coupled. The transformer is a device designed based on the concept of magnetic coupling.

Magnetically Coupled Circuit When two inductors are placed physically closed to each other then due flow in the first inductor, some flux is produced in the first inductor. part ot this flux will link with second inductor. therefore, using faraday’s law of electromagnetic induction this rate of change of flux will induce. some voltage across the second inductor. this induced emf will be additive or subtractive in nature. Magnetic coupling occurs, when there is no physical connection between two coils (or inductors). This coupling can be of either aiding type or opposing type.

This chapter first describes the concept of self inductance and mutual inductance and then explains how to determine the energy stored in magnetically coupled coils. A circuit model of a linear transformer is then illustrated. The chapter also shows the circuit model of ideal and iron‐core transformers. A transformer is said to be linear if the coils are wound on a magnetically linear material, a material with a constant magnetic permeability.

Conductors are used to connect elements. Circuit elements can also be connected through magnetic fields, called magnetically coupled. An inductor is basically a conducting coil. Instantaneous energy stored in a magnetically coupled circuit: w = 1 2 L 1 i 1 2 + 1 2 L 2 i 2 2 ± M i 1 i 2 where: M = "+" if both currents enter or leave the dotted terminals. M = "-" if otherwise.
