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.
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.

Plastic bobbin with 2, 50 and 500 turns of insulated copper wire and rotatable on vertical axis is mounted on a moulded plastic base, with leveling screws and four terminals, with magnetometer mounted at the center of the bobbin.
This demonstrates the action of electric current on a magnet.
