Power is very important to modern systems. From the smallest sensors, bionic implants, laptops, consumer products to satellites and oil platforms, it is important to be able to deliver power means other than classical wires or transmission lines. Wireless transmission is useful in cases where instantaneous or continuous energy transfer is needed, but interconnecting wires are inconvenient, hazardous, or impossible. An efficient method for wireless power transfer would also enable advances in such diverse areas as embedded computing, mobile computing, sensor networks, and micro robotics. The need to minimize energy consumption is often the main design driver in applications where devices need to operate without tethered. Energy consumption often restricts functionality in such applications. The work depicted in this paper is inspired by potential application of magnetic resonant coupling as a means for WPT from a source coil to a single load. It is observed that without the intermediate coil a LED is lit up to a maximum distance of 70 centimeter and with intermediate coil that lead is lit up to a maximum distance of 91 centimeter with voltage measured 2.2volts. Several experiments regarding this technique need to carry out for a better output and the day is not far when the need for wires will get obsolete.
