On the inductance coil storage principle is analyzed, the first analysis ofboth the extension to the structure and working principle of theinductance coil. Tesla coil inductance coil is wound into a wire, nature is a circle of the winded, the center of circle will add core or magnetic flux is also increasing, magnetic induction line increases inductance coefficient,increase the functional parameters of inductance coil.

The inductance coil is the main function of a filter function, mainly because of a self inductance principle. When the channel in the currentchanges, the coil itself automatically generate electromagnetic, coil conductor inside the reverse current, produces buffer, which cause the current to the range of variation is small. Similarly, when the current is reduced, the self generated electromagnetic field, produce the same to a current, supply current, so that the current decline speed is slow, when the current wave line graph became sleek neat. The charge discharge is equivalent to an energy storage process.

The inductor is in itself a storage element, its principle is based on themagnetic field energy storage. On current, the stored energy and the inductance and flowing through the relationship itself is: E = L*I*I/2.Because of the inductance with resistance at room temperature, there isresistance to consume energy, the ideal energy storage technology is the use of superconductors. The inductance coil storage is not mature, but there are case reports of application. But when current from zero to a maximum value of the energy storage principle of inductance coil,inductance coil electromagnetic field is itself produced reached its peak when the current reaches the steady state, the maximum value, if used asa superconductor wire link inductance two end and the power removed,inductance coil itself is a superconductor, the current will according to the original value in inductance short circuit in the loop inductance long flow,this kind of state is the energy storage state.
