Document Summary
It shares the same unit (henry) but has its own symbol (m). Essentially, it exists when the magnetic flux lines of one inductor cut into a second inductor, thus causing a change in that inductors flux. Assume that the secondary (right side here) is open therefore i2 = 0 and that current i1(t) is flowing into the primary as shown. If i1(t) is varying, then there is a voltage v1(t) being induced across the primary from the self-inductance, l1. Along with this self- induced voltage, there"s a voltage, v2oc, which is induced across the secondary due to the mutual inductance, m. If either coil were wound in the opposite direction, a + rate of change in one would induce a negative rate of change in the other. Transformers do not pass dc. di t dt di t d t mutual inductanc.
