How to Make the World's Simplest Motor: SciShow Experiments

The video tutorial demonstrates how to build a simple homopolar motor using a disk magnet, D battery, copper wire, and a screw. It explains the motor's operation, highlighting the conversion of electrical energy into mechanical energy through the Lorentz force. The tutorial also discusses the principles of electromagnetism and the inefficiency of this motor design due to continuous current flow, which quickly drains the battery.

Describe the process of how the electric current flows through the motor.

What are the limitations of the simple motor described in the text?
