Abstract: Technologies for providing DC arc protection in a DC socket include an electromagnet positioned in the DC socket configured to produce a magnetic field. The electromagnet is positioned to be adjacent to a contact region between one or more supply terminals of a DC socket and one or more prongs of a DC plug. As the DC plug is disconnected from the DC socket, a DC arc might form between one or more of the supply terminals and one or more of the prongs. The magnetic field produced by the electromagnet reduces the energy of the DC arc and reduces the time duration of the DC arc.
