							How To Use the Right Hand Rule to Find
the Direction of Magnetic Field due to a Current

   This Right Hand Rule (also known as the “Corkscrew Rule”) can actually
be used in two ways.

  1. For a straight (or straightish) current: point your thumb in the direc-
     tion of the current. Your ﬁngers will curl around in the direction of the
     magnetic ﬁeld due to the current.

  2. For a circular current (e.g. current loop or solenoid): curl your ﬁngers
     in the direction of the current. Then your thumb will point in the
     direction of the magnetic ﬁeld due to the current.
