Wireless power transfer (WPT) is the transmission of electrical power without wires and is based on technologies using time-varying electric, magnetic, or electromagnetic fields. magnetic power transmission A magnetic coupling is a coupling that transfers torque from one shaft, but using a magnetic field rather than a physical mechanical connection. Electric and magnetic fields, often referred to as electromagnetic fields or EMF, occur naturally and as a result of the Power generation, Power Transmission, Power distribution and use of electric power.. EMF is fields of force and is created by electric voltage and current. Not only do electrical power transmission products, but also mechanical power transmission products need to comply with the ATEX directive.

Magnetic couplings for power transmission between hermetically sealed areas. wireless power transmission is now commonplace in passive Radio Frequency Identification (RFID) systems [11], which derive their energy inductively, capacitively or radiatively from the tag reader. Over the past few years, various metamaterials have been designed and applied in antenna systems. And thus those who dont have access to electricity, even they can use it and it will make their life much better. Magnetic components are the norm in electric motors and non-contact drive couplings, but new developments could see magnets taking the place of mechanical gears in power transmission systems. Paul Stevens reports on novel magnet-based power transmission components and the advantages they offer designers. Electric fields are easily shielded or weakened by walls and other objects, whereas magnetic fields can pass through buildings, living things, and most other materials. The strength of the EMF is proportional to the amount of electrical current passing through the power line and decreases as you move farther away. And thus those who dont have access to electricity, even they can use it and it will make their life much better. Magnetic Bearings.
