The wireless Energy Transfer or Electromagnetic Energy Transfer works on the electromagnetic induction. It is done without help of physical wire and only directly wireless. Some Examples of this are Smartphones and some batteries. This can charge itself without connecting any physical wire to it and by keeping that device on some or the other surface and it charges automatically. This transformation of energy is done only on plastic or glass surface. On metal surface it is not possible because metals have free electrons for flowing in the circuit and plastics and glasses don't have free electrons to transfer and the can't get short circuit while flowing the wireless current and in meals it can cause short circuit and harm the whole device. This is also used to interchange some data from one device to another device. The working of that device is like the working of electric motor. When we pass electricity from copper wire then it produce magnetic field and that magneti...
