  1. The electric charges in motion produce magnetic fields.
  2. When a bar magnet brought close to the screen of a television we can observe that the picture on TV screen is distorted.
  3. The motion of electrons reaching the screen affected by the magnetic field of the bar magnet.
  4. This must be due to the fact that the magnetic field exerts a force on the moving charges.
  5. This force is called magnetic force.
