Emission coil and receive coil distance for 1 ~ 20 mm， i
f small current work can be appropriately increase receiving coil turns to increase transmission distance
If receiving distance increase it\'s need to add the coil turns.
In ractical application， it can change the turns of coil to adjust the power.
