**9.4 Procedure to Calculate Inductance**

In order to calculate the inductance of an inductor, we’re going to follow a certain procedure as we did in the case of capacitance of a specific capacitor. If it’s a procedure to calculate the inductance, first we’ll assume that a certain current is flowing through the inductor. Let current *i* is flowing through the inductor.

As a second step, we will calculate the magnetic field of the inductor by applying Ampère’s law. Calculate the magnetic field by applying Ampere’s law, which is integral of **B** dot *d***l** integrated over a closed loop *C* is equal to *μ**0* times *i* inclosed.

As a third step, once we’ve found the magnetic field of the inductor, we will calculate the magnetic flux through the cross-sectional area of the inductor.

Once we determine the flux through the cross-sectional area of the inductor, then the last step is calculating the inductance from its definition. And that is *L* is equal to *N* times number of terms times the magnetic flux divided by the current.
