Solution: To calculate the mutual inductance M, we first need to know the magnetic flux through the rectangular loop. The magnetic field at a distance raway from the straight wire is B=µ0I/2πr, using Ampere’s law. The total magnetic flux ΦBthrough the loop can be obtained by summing over contributions from all differential area elements dA=l dr:
The mutual inductance \ (M_ {21}\) of coil 2 with respect to coil 1 is the ratio of the flux through the \ (N_2\) turns of coil 2 produced by the magnetic field of the current in coil 1, divided by that current, that is, \ [M_ {21} = \dfrac {N_2\Phi_ {21}} {I_1}. \label {12.24} \] Similarly, the mutual inductance of coil 1 with respect to coil 2 is
The self inductance of the coil is (from previous lecture) , This is (ideally) constant inside the volume of the coil and zero outside it. This enables an energy density or energy per unit volume to be calculated. Even though this was derived for a specific ideal case it applies to any magnetic field.
Mutual Inductance is the basic operating principal of the transformer, motors, generators and any other electrical component that interacts with another magnetic field. Then we can define mutual induction as the current flowing in one coil that induces a voltage in an adjacent coil.
