Inductance characteristics

Inductance is a measure of the coil to produce the physical quantities of the ability of electromagnetic induction. When the non-steady-state current through the coil into a changing magnetic field is generated around the. Pass into the coil, the greater the power, the higher the incentive out of the magnetic field strength, and vice versa (before reaching saturation magnetic induction). Inductance is generally divided into two kinds of air-core inductor core inductor. Air core inductor inductance is a given value of the constant, simple application.

Large core inductor industrial applications more accurate inductor money or not is a critical issue, both from the theoretical and practical application of major significance.

By the equation L = μ × Ae * N2 / l · analysis. L represents inductance, μ represents the magnetic permeability of the magnetic core, Ae represents the cross sectional area of the magnetic core, and N represents the coil turns, LM indicates the magnetic path length of the core. Therefore, when the production of an inductor after molding, Ae, N, lm are given value, then affect inductance factory measure only magnetic permeability μ.
