Experimenters Corner By; Lorrie Matchett....Keeping it simple & cheap....Energy transfer between the coils is around 100 milliamps or so depending on the distance and its resonance frequency. Wireless electricity transfer via magnetically coupled resonance.is based on using coupled resonance. Two coils that resonant at the same frequency tend to exchange energy efficiently and by winding them in a bifilar manner increase this efficiency.. This type of winding, invented by Nikola Tesla enhances the magnetic field which means more power transfer. In this setup, I used a fifteen volt d/c power pack and converted it into alternating current with a custom build electro-mechanical oscillator which resonates at about 20Khz...Higher oscillating frequencies / voltage, increases the energy transfer distance between the coils, yet to be experimented with...




The oscillating a/c magnetic field of the transmitting coil induces eddy currents, creating a magnetic field of its own within the aluminum sheet and in turn blocks the energy transfer to the adjacent coil...Most sheet metal materials such as aluminum, steel, iron, brass or copper will block the transfer of energy, but will other metals do the same? The challenge to all the experimenters is to improve on this design.... ( epowerplus@gmail.com ) Note: The aluminum sheet used in this video is .080", not as seen....my mistake.
