The self-induced emf in a circuit is directly proportional to the time rate of change of the current (dI/dt) multiplied by a constant (L). This constant is called the inductance (or more precisely, the self inductance) and is determined by the geometry of the circuit (or more commonly, by the geometry of individual circuit elements).

A solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field. If the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

In electromagnetism and electronics, inductance is the property of an electrical conductor by which a change in electric current through it induces an electromotive force in the conductor. It is more accurately called self-inductance.
The symbol L for inductance was chosen to honor Heinrich Lenz (1804–1865), whose pioneering work in electromagnetic induction was instrumental in the development of the final theory.

Equation

L = µ₀ * N² * A/l

where:
N - number of turns N
I - length
A - area of the cross-section
µ₀ - 1.25664 * 10^-6 T*m/A. The vacuum permeability

*This is a universal app that work for both iPhone and iPad.
