ElectroMagnet
ElectroMagnet are found in current carrying conductor. When the conductor conducts current the conductor generates a Magnetic Field that can attract any metals like Ferrite, Zink, ... just like a Lodestone's Magnet


 * 1) /Straight Wire Conductor/
 * 2) /Coil of several Turns/
 * 3) /Dipoles/
 * 4) /Permanent ElectroMagnet/

ElectroMagnetic Induction
In current carrying conductor when conducts current generates Magnetic field B which in turn induce one voltage that has the same polarities with the current polarities and an induce voltage that has the opposite polarities to the current polarities

ElectroMagnetic Force
In current carrying conductor when conducts current generates Magnetic field B which in turn produce a Magnetic Force F perpendicular to the direction of current flow
