Needle Stand Magnetic

Description

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 demonstrates the action of electric current on a magnet. A cobalt steel needle with agate bearing supported by pivot is mounted on a plastic base and surrounded by rectangular frame fitted with terminals.

Description

A wooden table supports a plastic ring wound with three coils of 5, 10 and 20 turns of insulated copper wire, connected to terminals on the base.

Description

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.
