| Coiled conductor and its magnetic field |
An easy method of determining the magnetic field and the north and south
ends of an eletromagnet produced by a coil is using the right hand rule
#2 for conventional current flow, also known as RHR#2. Grasp the coiled
conductor in such a way that your fingers curve in the direction of
conventional current, from positive to negative. The direction where
your thumb extends to is the north (N) end of the electromagnet produced
by the coil.
