The first coil is attached to the power source while the second coil to the light bulb.When the power is switched on the first coil converts the electricity into magnetic field ,which is oscillating at a particular frequency i.e, AC source.The second coil at the receiver end converts the magnetic field into electricity. Principle of WitricityWitricity works on the principle of mutual induction between the two coils.There are two copper coils arranged one at the sender end and other at the receiver end. As these are becoming daily needs to the present generation wireless energy transfer. In cell phones signals are sent in the form of micro waves whereas in this mode of transition electricity is transferred in the form of magnetic rays.These rays are not harmful to humans.HistoryThe term WiTricity was used for a project that took place atMIT, led byMarin Soljacicin 2007.The MIT researchers successfully demonstrated the ability to power a 60wattlight bulb wirelessly, using two 5-turn copper coils of 60cmdiameter, that were 2m (7ft) away, at roughly 45% efficiency and roughly 90% efficiency at a distance of 3 feet.Need of WitricityNow-a-days there is a rapid increase of electronic goods like cell phones ,laptops ,I-pods etc., which rely on the chemical storage of energy by the battery which need to be recharged frequently. ![]() ![]() ![]() This is not like wireless transmission of signals which we used in the cell phones.
