What is inductance effect
An inductive device is called an inductor (inductor, which is generally referred to as an inductor in Chinese), and the inductor is usually a coil, which can gather the magnetic field.
The ratio of the change of the magnetic flux to the amount of the change of the current is called self inductance
According to Lenz's law, the flux tends to resist the change of electric current by the induced voltage (back EMF).
Any current in the circuit produces a magnetic field, and the magnetic flux of the magnetic field acts on the circuit.
