The Sci Guys: Science at Home - SE3 - EP8: Simplest Electric Motor - Homopolar Motor

Welcome to science at home episode eighth, season three. In this episode we will be building the simplest electric motor. The simplest electric motor is also known as a homopolar motor. The simplest electric motor works by harnessing a force known as Lorentz force when an electron passes through the magnetic field the be base of our motor. This motor is homopolar because its polarity is constant as it functions. By the end of this video you will be able to describe what a Lorentz force is, how it is able to spin the copper wire of our motor and how to build the simplest electric motor also known as a homopolar motor.
