Product Specification Sheet
Faraday’s Disc
Model Number: MTME-30
Faraday’s Disc is a compact electromagnetic induction apparatus designed to demonstrate the conversion of mechanical energy into electrical energy. Micro Technologies supplies the apparatus with a copper disc fitted with a turning handle, rotating between the poles of a horseshoe magnet. One electrical contact is connected to a pillar supporting the disc, while another makes contact through a brush bearing on the edge of the disc. Rotation of the conductive disc within the magnetic field produces an electrical potential that can be investigated using suitable measuring equipment.
Product Specification
The Faraday’s Disc is a classic electromagnetic apparatus used to demonstrate the generation of electrical energy through the motion of a conductor in a magnetic field. It provides a simple and highly visual arrangement for investigating fundamental electromagnetic induction and generator principles.
The apparatus incorporates a copper disc mounted so that it can rotate between the two poles of a horseshoe magnet. Copper provides a conductive path through which charge can move as the disc rotates within the magnetic field.
A manually operated turning handle is connected to the disc. Rotating the handle supplies mechanical energy to the system and causes the copper disc to move continuously through the magnetic field.
Micro Technologies provides two electrical contact points for accessing the generated electrical potential. One contact is connected to the pillar supporting the disc, while the second is connected to a brush bearing against the edge of the rotating disc.
As the copper disc rotates in the magnetic field, charges within the conductor experience a magnetic force. This produces a potential difference between different radial positions on the disc, allowing an electrical output to be detected using suitable sensitive measuring equipment.
The apparatus provides a direct demonstration of the relationship between mechanical motion, magnetic fields, and electrical generation. Changing the rotational direction can also be used to investigate the corresponding change in output polarity.
Faraday’s Disc is also commonly associated with the principle of a homopolar generator, providing a useful experimental arrangement for exploring one of the simplest forms of continuous electromagnetic generation.
Its manual operation eliminates the need for a separate drive motor, while the exposed disc and magnet arrangement makes the essential components of the experiment clearly accessible for observation.
