Wireless Power Transmission Roopesh Dhara Abstract In today’s rapidly growing industries power source is a major aspect of any field. The use of wires is becoming redundant day by day. Considering this as a major issue, the fundamental idea here is to wipe out the utilisation of wires. This may be achieved by implementing wireless power transmission techniques which are far better than the standardised methods of transfer of power. Using close range and far range methods is dependent on the medium of its application. Keywords: Electricity, Magnetism, Electromagnetism, Magnetic induction, Power coupling, Resonance, Resonating magnetic coupling, wireless power transmission, wireless power transfer. 1. Introduction To be able to understand the concepts of wireless power transmission one must be thorough with the following concepts. Electricity- The transfer of electrons through a conductor which is the simplest way to supply energy between two points. Magnetism- An attracting or repelling force acting on materials which possess certain properties. Electromagnetism- Interdependence of time varying electric and magnetic fields. Fundamentally, a magnetic field is generated from an oscillating electric field and vice – versa. Fig 1: Current through wire generating magnetic field. In a wire, when current I flows, it produces a magnetic field B which is a vector quantity which encompasses itself on the wire. The direction of current and magnetic field are directly proportional. In a coil, the magnetic field generated is widely dispersed into all directions. Fig 2: Current through coil producing magnetic field.
