Drag and drop the boxes into the correct order.



  • The membrane pushes out a pressure wave through the air
  • As the current alternates, this process repeats
  • Due to the motor effect, the current-carrying wire in the magnetic field feels a force upwards
  • The coil experiences a force in the opposite direction
  • The coil moves upwards, pushing up a membrane
  • A current passes through the coil of wire
  • A coil of wire sits in a uniform magnetic field
  • The current through the wire changes direction
  • The coil moves downwards, pulling the membrane with it

This is your 1st attempt! The marking algorithm gives more marks for getting the right order first time.
