Working Principle:

           An electromagnet is simply a coil of wire.  It is usually wound around an iron core.  However, it could be wound around an air core, in which case it is called a solenoid.  When connected to a DC voltage or current source, the electromagnet becomes energized, creating a magnetic field just like a permanent magnet.   The magnetic flux density is proportional to the magnitude of the current flowing in the wire of the electromagnet.

           The polarity of the electromagnet is determined by the direction of the current.  The north pole of the electromagnet is determined by using your right hand.  Wrap your fingers around the coil in the same direction as the current is flowing (conventional current flows from + to -).
