Disclosed are an arc path generation unit and a direct current relay including the same. An arc path generation unit according to various exemplary embodiments of the present disclosure comprises a Halbach array and a magnet part which form a magnetic field in a space part formed in the arc path generation unit. The magnetic field formed by the Halbach array and the magnet part forms an electromagnetic force, together with the current applied to each of fixed contacts. The electromagnetic force formed near each fixed contact is formed in a direction going away from the center of the space part, or in a direction going away from each fixed contact. Therefore, generated arcs can be rapidly suppressed and discharged through induction by the electromagnetic force.

An electrical relay (2) includes an electromagnetic drive system for providing bi-directional drive. The electrical relay (2) includes a first a coil (212) and a second coil (213). A current is supplied to the coils (212) and (213) in opposite directions. The two coils (212) and (213) can be used to accelerate the armature in either direction in relation to the two contacts. This can be used to drive the armature to either one of the contacts and to accelerate and decelerate the armature during a single transit. In the latter regard, the armature can be accelerated and decelerated to shorten the transit time, reduce bounce, reduce wear on the contacts, and allow for different contact material options.
