Abstract
An electrical apparatus comprises a main body, a pivotal part pivotally connected to the main body, a first coil mounted on the main body, and a second coil mounted on the pivotal part. The first coil at least partly passes through the second coil to form an electromagnetic coupling between the first coil and the second coil that wirelessly supplies power between the main body and the pivotal part.
