Magnetic resonances is a kind of wireless transmission system, which can take best advantage of the wireless power transfer technology. Magnetic resonance adopts the principle of the coil induction in space and the equivalent circuit analysis,which can better analyze the frequency curve of voltage and power transmission. In addition, according to the principle of spatial distribution, it puts space coil in suitable place, analyzes the relationship between the numerical value and direction of air-core coil, proposes three states of the wireless power： coupling, critical coupling and under-voltage coupling. In addition, based on the related experiment,we also compare with other experimental results,specifically get the practical condition of wireless transmission electricity, and put forward some relevant suggestions.
