DC Motor – 5K40.10


  • Place the battery between the uprights.
  • Place the coil in the bent sections above the magnet.
  • The coil should start spinning because each half turn the current is flowing through the winding and repelling off the magnet.
  • As it rotates the current stops but momentum will carry the other side on around until the loop again makes connection with the current from the battery.
