Product Overview
This set includes two classic devices that illustrate the fundamental principles of electromagnetism and electrical generation: Barlow's Wheel and Faraday's Disc.
Barlow's Wheel
An early example of a homopolar motor, Barlow's Wheel demonstrates the interaction between electric and magnetic forces. Powered by 2 AA size batteries, this historical experiment shows how electric current creates motion in a magnetic field. It is often demonstrated in tandem with the Faraday's Disc to highlight the relationship between electricity and magnetism.
Faraday's Disc
The Faraday's Disc is a groundbreaking invention in the history of electrical engineering, known as the earliest DC electrical generator or homopolar generator. This copper disc, powered by a hand crank, rotates between the poles of a horseshoe magnet. As the disc turns, electrical current is generated, and the voltage difference can be detected by connecting a voltmeter to the provided terminals. This experiment highlights the principle of electromagnetic induction.
Together, these devices offer valuable hands-on demonstrations for understanding basic principles of electromagnetism and electricity generation.
