The Inductance for a Solenoid calculator computes the inductance based on the relative permiability, cross-section area, number of coils on the bobbin and the length of the coil.

Solenoid Inducatance (L): The calculator returns the inductance in Henries. However, this can be automatically converted to compatible units via the pull-down menu.
The Inductance for a Solenoid equation computes the inductance of a coil of wire on a bobbin.
The bobbin is a spindle shape object that is often used in a transformer. In transformer terminology the bobbin is the structure on which a coil of wire is wound.
A transformer is for stepping up or stepping down an AC power source by using the principle of magnetic induction between the transformer's two wire windings. There are a number of calculations in designing or building a transformer.
In general inductors use a ferrite core. Reducing the Inductance leakage will lead to increase of capacity. The formula for the Inductance of a Solenoid is:
`L = ( mu_0 * mu * A_c * n^2)/l`
