FAQ

1. What is inductance?

Inductance is a property of closed magnetic circuit and a physical quantity.When the coil passes through the current, a magnetic induction is formed in the coil, which in turn generates an induced current to resist the current passing through the coil.This interaction between the current and the coil is called electrical reactance, or inductance, after the American scientist Joseph Henry.

Inductance is a circuit parameter that describes the induced electromotive force effect in this coil or in another coil due to the change of coil current.Inductance is the general term of self - inductance and mutual inductance.

The units of inductance are expressed as L, and the units are Henry (H), millihenry (mH), microhenry (muh), 1H=10^3mH=10^6 muh.High school physics does not do the calculation of inductance requirements.

Self and mutual sense

(1) self-perception

When an electric current passes through the coil, a magnetic field is created around the coil.When the current in the coil changes, the magnetic field around it changes accordingly. This change in the magnetic field causes the coil to generate its own induced electromotive force (induced electromotive force) (which represents the voltage at the end of the ideal source of the active element). This is called self-induction.

(2) mutual inductance

When two inductors are close to each other, the change in the magnetic field of one inductor affects the other, which is called mutual inductance.The mutual inductance depends on the degree to which the self-inductance of the inductance coil is coupled with the two inductance coils.
