The unit of inductance -- Henry

Inductor capacitor depends on four factors:

> coil number: the more coils, inductance more strong.

> surround material coil (core)

> cross-sectional area of the coil inductance: area bigger, stronger.

> coil length: short circle refers more narrow (or overlapping) coil, it means that the stronger the inductance.

The iron on the wire core inductor, inductance generated than air or any nonmagnetic core line much.

Standard unit of inductance is Henry. As Henry number equation calculatingthe inductor:

H= (4 * 3.14159 * * * turns turn number of coil area * (MU) / coil length * 10000000) area of the coil and the unit of length is the meter. The symbol Muis used to represent the permeability cores. Air permeability is 1, and the permeability of the steel may be 2000.
