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.
For demonstrating that some metals are magnetic whilst others are not and for general ‘Metal Identification’ exercises.
Comprises sixteen discs, 25 mm.
diameter 2 each of Mild Steel, Stainless Steel, Brass, Zinc, Nickel, Silver, Bronze, Aluminium and copper.
One of each is stamped with the name of metal.
the other is unmarked.
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.
