The inductor itself is an energy storage element, storing energy in the form of a magnetic field. Since inductors have resistance at room temperature, resistance consumes energy, so many energy storage technologies use superconductors. Inductors are characterized by the fact that the current through them cannot change abruptly. The process of storing energy in an inductor is the process of current from zero to a steady-state maximum. When the inductor current reaches a steady state maximum, if you use a non-resistive (such as superconductors) short inductor two ends and remove the power supply, if the inductor itself is also a superconductor, then the current will be according to the original value of the short circuit in the inductor flow for a long period of time, the inductor this state is the state of energy storage.

Inductive energy storage, as one of the many energy storage technologies, has extremely important applications in modern science and technology, such as plasma physics, controlled nuclear fusion, electromagnetic propulsion, high-power lasers with repetitive pulses, high-power radar, the generation of strong streams of charged particle beams and strong pulses of electromagnetic radiation.

Inductive coils are widely used in electrical products, where the general wire needs to be wound many times and the wire thickness is low. As a common electronic component, the common quality problems are short circuit between coils, wire breakage, and heat generation. Generally speaking, ensuring the quality of inductor coils can improve the quality level of related products. In addition to the influence of the coil enameled wire, it is mainly to pot the coil with glue. Inductor coil glue can both play the role of insulation of the coil, inductor coil potting can also be fixed on the coil, to prevent vibration brought about by the quality of electrical products.
