Electrical connectors use magnetic repulsion for orienting themselves in the right polarity and magnetic attraction for holding together. When inserted into the ends of a conduit, a pair of these electrical connectors can transfer electricity through the conduit. Each electrical connector includes a housing with top and bottom surfaces and a fixed and a movable terminal both of which are recessed below the top surface of their respective, parallel passages. A spring controls terminal movement. Each terminal carries an electrical contact. A torus-shaped magnet surrounds the contact of the contact in the movable terminal so that its magnetic field energizes that contact. The magnets in movable terminals of each electrical connector are oriented in the same way so movable terminals of electrical connectors repel each other but fixed terminals attract movable terminals from their passages and into the passages of the fixed terminals so that two electrical connectors lock together.
