A magnetic coupling is a device that transmits torque between two shafts via a magnetic field, eliminating the need for a physical mechanical connection. This technology is widely used in various propulsion systems, such as vehicles and remotely operated underwater vehicles, to transfer torque from electric motors to propellers.

ELIX Wireless employs Magneto Dynamic Coupling (MDC) technology, which integrates rotating magnets with a built-in motor generator system for wireless power transfer.

A similar technology is showcased by the WiPASS Magnetodynamic Wireless Power Transfer (WPT) system. This system features a transmitter that generates a time-varying magnetic field, while the receiver consists of a magnet that moves within a coil. The changing magnetic field produced by the transmitter applies a force or torque on the magnet, causing it to move or rotate.
