The magnetic field can be seen as a pattern of circular field lines around a wire. A single way to find the torrent of a magnetic field is with a compass, as a display by a long directly electrically conductive wire. Auditorium investigation can determine the magnitude of the area. In the right-hand rule, the thumb indicates the direction of current flow and other fingers indicates the direction of the magnetic field around the wire. Let's take an awesome trivia quiz about Magnetic Field Of Current.
