Motors are machines which convert electrical energy to mechanical energy. Drones require motors to create a necessary thrust during flight. 

HOMOPOLAR MOTOR EXPERIMENT (15 mins) 

Use this experiment to show how a basic motor works. It uses neodymium magnets, a AAA battery and a copper coil. Watch the video to understand the working.

➔ Build and show to explain how a motor basically works
