Inductance is the ratio of the magnetic flux generated by the alternating magnetic flux around the inside of the wire when it passes through the alternating current in the wire, and the ratio of the magnetic flux of the wire to the current that produces the magnetic flux. When DC current is passed through the inductor, only a fixed magnetic flux is present around the inductor and does not change with time.
However, when AC current is passed through the coil, the magnetic lines of force around it will change with time. According to Faraday’s Law of Electromagnetic Induction—Magnetism, it is analyzed that changing magnetic lines of force generate induced electric potentials at both ends of the coil. This induced electric potential corresponds to a “new power source”. When a closed loop is formed, this induced potential generates an induced current. From Lenz's law, it is known that the total amount of magnetic flux generated by the induced current tries to prevent the change of the magnetic flux. The magnetic force line change comes from the change of the external alternating power supply, so from the objective effect, the inductance coil has the characteristics of preventing the current change in the alternating current circuit. Inductive coils have characteristics similar to the inertia in mechanics. They are called “self-sensing” electrically. Usually, sparks occur when the knife switch is turned on or the knife switch is turned on. This self-inductance phenomenon is very High induced potential caused by.
In short, when the inductor coil is connected to the AC power supply, the magnetic lines inside the coil will change with the alternating current, resulting in electromagnetic induction in the coil. This electromotive force generated by the current change of the coil itself is called "self-induced electromotive force." It can be seen that the inductance is just a parameter related to the number of coils, size, shape, and medium. It is a measure of the inductance of the coil and has nothing to do with the applied current.
