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…
