Magnetic field Demo, long solenoid

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

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.

Description

Both sides glass tops, 20 mm diameter. With both sides glass tops, 20 mm diameter.
