An inductively coupled transponder comprises an electronic data carrying device, usually a single microchip, and a large coil that functions as an antenna. Inductively coupled transponders are almost always operated passively.
Implementations
Devices that use inductive coupling- Transformer for AC power coupling and inductive charging
- Graphics tablet
- Radio Frequency Identification
A variety of inductive charging products charge batteries using inductive coupling, such as WiTricity.
Low frequency induction
Low frequency induction is an unwanted form of inductive coupling, which can occur when a metallic pipeline is installed parallel to a high-voltage power line. The pipeline, which is a conductor, and is insulated from the earth by its protective coating, can develop voltages which are hazardous to personnel operating valves or otherwise contacting the pipeline.
