Hans Christian Oersted. In 1820, a Danish physics teacher observed that the current moving through a wire moved the needle on a nearby compass. when the current was reversed, the compass needle was deflected in the opposite direction. these magnetic effects ceased when the current in the wire stopped.
For example, if the wire and the base material get too close, the current will rapidly increase, which in turn causes the heat to increase and the tip of the wire to melt, returning it to its original separation distance. The direction of current used in arc welding also plays an important role in welding.
