Transfer of power wirelessly through magnetic resonance is a hot topic these days not only for low power consumer electronics like laptops, cell phones etc. but also for high power applications like electric cars, trains and for medical implants as well. In the University of Bergen, the magnetic resonance technique has been used for level measurements and may be used for material properties. Our objective here is the efficient power transfer using printed circuit board (PCB) coils. The study is performed for the efficiency variation with distance in air. The efficiency is found to be maximum at resonance frequency. The effect of the external factors like steel sheet and salt-water solution of fixed concentration is studied. Both of these obstruct the power transfer efficiency to a certain extent. Steel is more obstructive than salt-water solution of the concentration that we have used.
