5.1 Introduction. Inductance is one of the three basic, passive, circuit element properties. It is inherent. in all electrical circuits. As a single, lumped element, inductors find many uses. These. include as buffers on large transmission lines to reduce energy surges, on a smaller scale. to serve a similar function in electronic circuits, as ...
Experiment No. 6: Self Induction and Mutual Induction
effect is called mutual-induction. Consider the Figure 6.2, current flowing through the coil of inductance L 1 builds up a magnetic field (flux) around itself. A part of this flux which links only coils 1. The other part links both the 1 and 2 coils and therefore is a component of mutual flux. This mutual flux sets up an induced e.m.f. in coil L 2

Example 11.4 Mutual Inductance of a Coil Wrapped Around a Solenoid. long solenoid with length l and a cross-sectional area A consists of N1 turns of wire. An insulated coil of N2 turns is wrapped around it, as shown in Figure 11.2.4. Calculate the mutual inductance passes through the outer coil.

In the case of two solenoids, the mutual inductance M may be calculated exactly. Let the inner solenoid have length l and diameter 2a, the outer solenoid diameter 2b, as shown below. In general, mutual inductance depends only on the geometry and number of turns in each coil, as in this example.

Mutual Inductance. The formula for mutual inductance is. = 1 2. = the coefficient of coupling (dimensionless) 1, 2= inductance of each coil (H) The coefficient of coupling depends on factors such as the orientation of the coils to each other, their proximity, and if they are on a common core.

So coefficient of mutual inductance may also defined as 'induced e.m.f. produced in secondary when a unit rate of change of current is made in primary circuit'. The mutual-inductance of two circuits is related to their self-inductance L 1 and L 2. If 'I 1' be the current through primary then the flux 'ɸ 1' linked with it is given by:
