magneticcoupling
Magnetic coupling is the transfer of energy or mechanical torque between two systems through a magnetic field, without or with minimal physical contact. In electrical engineering, it commonly refers to mutual inductive coupling between magnetic circuits or coils, as in transformers or inductive power transfer. In mechanical engineering, magnetic couplings provide non-contact torque transmission across a barrier, preserving hermetic sealing or containment.
Principles: When current flows in one conductor, it creates a changing magnetic flux that links another circuit,
Types: Core-based transformers use a magnetic core to channel flux and maximize M. Air-core couplings rely on
Applications: Power transformers, inductive charging (wireless charging mats and battery systems), sealed-pump drives, isolation of sensitive
Considerations: Design must manage core losses, eddy currents, and hysteresis; use laminated or ferrite materials to
