This apparatus spins an electrically charged brass wheel spin, without the aid of a motor.
When the wheel electrified by a voltage source (battery), the slotted brass disc sets up eddy currents throughout the structure.
This electricity is then attracted to 4 strong neodymium magnets, causing the wheel to spin.
This apparatus demonstrates the magnetic field patterns associated with the different shapes of current carrying conductors.
Comprises three conductors, each of different shape/configuration – straight rectangular, circular loop and solenoid all mounted on a plastic base.
Each configuration is provided with a pair of 4 mm sockets to connect them to a low voltage DC power source, with output current not exceeding 5A With the included iron filings and 8 magnetic compasses, you can investigate the associated field and flux patterns.

Laplace Apparatus works without mercury.
The study of Lorentz’s force is a crucial topic of introductory physics courses and interaction between electric currents and magnetic fields is a major issue of electromagnetism.
Power supply is required but not included.
For demonstrating that some metals are magnetic whilst others are not and for general ‘Metal Identification’ exercises.
