Self Induction and Self Inductance and Derivation of Inductance

Self Inductance: Self inductance is the ratio of the induced emf across a coil to the rate of change of current through it, denoted by L and measured in Henry (H). Lenz''s Law : The induced emf opposes the change in current, which is why there is a negative sign in the equation, following Lenz''s Law.

where is defined to be the mutual inductance between the two devices. The minus sign is an expression of Lenz''s law. The larger the mutual inductance, the more effective the coupling.For example, the coils in Figure 1 have a small compared with the transformer coils in Chapter 23.7 Figure 3..
