Abstract
An electromagnetic connector is disclosed that is configured to form a first magnetic circuit portion comprising a first core member and a first coil disposed of the first core member. The electromagnetic connector is configured to mate with a second electromagnetic connector, where the second electromagnetic connector is configured to form a second magnetic circuit portion comprising a second core member and a second coil disposed of the second core member. The first core member and the second core member are configured to couple the first coil to the second coil with a magnetic circuit formed from the first magnetic circuit portion and the second magnetic circuit portion when the electromagnetic connector is mated with the second electromagnetic connector. The magnetic circuit is configured to induce a signal in the first coil when the second coil is energized.
