Flemings Left/Right Rule - Effect of current

• • Left thumb = Motor
  • left index finger= Magnetic field
  • Left middle finger = Current
• • Right thumb = Motor
  • Right index finger = Magnetic field
  • Right middle finger = induced EMF
• Left hand rule is for motors, as for the right, the rule is for generators
