ElectroMagnet

[edit | edit source]

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

[edit | edit source]

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

[edit | edit source]

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
