flemings left-hand rule

• what is the motor effect?

  when a conductor carrying a current is placed in a magnetic field the magnet producing the field and the conductor exert a force on each other
• what factors affect the size of force on a conductor?

  • magnitude of current flowing through conductor
  • strength of magnetic field that conductor is placed in
• instructions for Fleming's left hand rule:

  • hold thumb, 1st finger & 2nd finger of left hand at right angles
  • thumb = motion ( force )
  • 1st finger = magnetic field ( N to S )
  • 2nd finger = current ( + to - )
• what would increase the size of the force on a conductor?

  • increasing the size of the current
  • using a stronger magnet
