How to use a Barlows Wheel Apparatus

1. Magnet:

A magnet, usually in the form of a horseshoe magnet, is positioned such that the poles are close to the copper disc.

1. Axle:

The axle serves as the axis of rotation for the copper disc.

1. Power source:

Initially, a small amount of external force may be needed to start the rotation of the wheel. This can be provided manually, after which the rotation continues due to the induced current.

1. Electric circuit:

The copper disc is connected to an electrical circuit. When the disc rotates, it cuts across the magnetic field lines, inducing an electromotive force (emf) in the disc, which causes an electric current to flow through the circuit.

1. Load:

A resistor or other load can be connected to the circuit to demonstrate the generation of electricity and its ability to do work.
