P3.3.1 - The Motor Effect

  • Placing a wire with a current in a magnetic field (between two magnets) makes the wire experience a force called "The Motor Effect".
  • This force is at its maximum if it is held at 90 degrees to the magnetic field.
  • The force can increase by:

 - Increasing the strength of the magnetic field

 - Increasing the size of the current.

  • The direction of the force is reversed if…
