Wireless energy transfer is the transmission of electrical energy from a source of energy to an electric charge without any conductive physical connection. Wireless electricity ensures that cell phones, laptops, iPods and other electrical devices change by themselves, without plugging them in to prevent plugs from having all kinds of cables. Wireless energy transfer is when the magnetic field is transferred at close range. The magnetic field is created by inductive coupling between wire coils or electric fields by capacitive coupling between electrodes. The most common form of wireless energy transmission is carried out by direct induction followed by resonant magnetic induction. The carrier flows inducing in the inductor can be captured by another inductive coil which can produce an induced flow between the receiver coils coupled to the primary coil. Since this technique uses the magnetic field to transfer electrical energy, the flux it produces in the primary coil must be in high density with the high frequency. Thus, the tesla coil is used as a transmitter to produce high voltage, high frequency and low alternating current in order to produce high density flux. In this work, a tesla coil is a major part of the transmitter component in wireless electricity devices and need to be developed in order to demonstrate how the magnetic induction is coupled to perform a wireless energy transfer. In addition, the construction of winding coils of the Tesla coil would be the great effects in order to provide electricity to supply a charge without wires over distances. The advantages of the wireless electrical system would be completely eliminating existing cables for electrical appliances between power supplies. With wireless electricity, the electrical system will be safer because it will prevent the user from electrocution of the current and power failure due to short circuit and failure or power loss in the cable would never exist.
Working
The power of the Tesla coil lies in a process called electromagnetic induction, ie a changing magnetic field creates an electrical potential that forces the current to flow. In contrast, the flowing electric current generates a magnetic field. When electricity flows through a coiled wire coil, it generates a magnetic field that fills the area around the coil in a particular pattern, shown by the lines of the image to one side:
