OEM Enamelled Wire Wireless Charger Receiving Induction Air Coil

Inductance is the ratio of the magnetic flux in a wire to the current producing the alternating flux in and around the wire when an alternating current passes through it.
When the dc current passes through the inductance, only fixed magnetic field lines are present around it, which does not change with time. But when an alternating current passes through a coil, it is surrounded by magnetic field lines that change over time. According to the analysis of Faraday's law of electromagnetic induction, magnetic generation, the changing magnetic field lines will generate an induced potential at both ends of the coil, which is equivalent to a "new power source". This induced potential generates an induced current when a closed loop is formed. Lenz's law knows that the total amount of magnetic field lines produced by an induced current should try to prevent the change of the original magnetic field lines. Since the original magnetic field line change comes from the external alternating power supply change, so from the objective effect, the inductance coil has the characteristics of preventing the current change in the AC circuit. The inductance coil has a characteristic similar to the inertia in mechanics, which is called "self-induction" in electricity. Usually, sparks will occur at the moment when the knife switch is opened or switched on. This is caused by the phenomenon of high induction potential generated by self-induction.
In short, when the inductance coil is connected to an AC power supply, the magnetic field lines inside the coil will change constantly with the alternating current, causing the coil to continuously generate electromagnetic induction. This electromotive force due to the change in the current of the coil itself is called "self-induced electromotive force".
It can be seen that the inductance is only a parameter related to the coil number, size and shape and medium, it is the measurement of the inductance coil inertia and has nothing to do with the applied current.
