Magnetic ring inductance coils
The magnetic ring inductance coil is mainly used for the switch power supply.
For manufacturing the filter inductor (inductance coil) and transformer, the electromagnetic inductance elements wound with insulating conductors (such as enameled wire, cotton covered wire and so on).
Such coil is also the one of common components of the electronic circuit.
The relevant products include common mode filter and so on.
It has such characteristics as low consumption, high magnetic conductivity, low cost and so on.
I.
Self-inductance and mutual inductance
(1) Mutual inductance
When the current passes through the coil, there will be magnetic field around the coil.
When the current in the coil changes, the magnetic field around the coil will also change, the changing magnetic field can make the coil itself to have induction electromotive force (the induction electromotive force is used to express the terminal voltage of the ideal power supply of the active element), this is self inductance.
(2) Mutual inductance
When two inductance coils mutually approaches, change of the magnetic field of an inductance coil will affect another inductance coil, this influence is just mutual inductance.
Size of mutual inductance depends on the coupling degree between the self-inductance of the inductance oil and two inductance coils.
If one capacitance is connected to the DC power supply, there will be charging at the time when the power supply is switched on.
Because Q=CU, and there will instantaneous directional movement of charge in the circuit and short-time current.
However, after it is stable, the charge in the circuit will not move, and there will not be current in the circuit.
When the circuit changes, the voltages at both ends of the capacitance will reduce, the capacitance will discharge.
Because Q=CU, after it is stable, there will not be function of current in the circuit.
Because the voltage of AC power supply continuously changes, and thus the capacitance will continuously charge.
Thus, the current seems to pass through the capacitance, but the fact is not so.
