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.
Comprising iron U-shaped core of circular section, with armature and carrying hook.
Wounded with insulated copper wire and provided with connectors for use on 4-6 volts D.C.
This demonstrates the action of electric current on a magnet.
