A former with terminals and engraved circle marked 0 – 180° – 0 figured every 45°, wound with 30 turns of insulated copper wire, complete with a magnetic needle 75 mm long and a pivot for the needle.
For investigating the magnetic field associated with a solenoid coil.
Coil size 51 x 92 mm.(diameter x length) approx.,diameter of wire 1.5 mm.
Magnetic field Demo, long solenoid
For ordinary magnets, iron bars, strips etc.
Consists of a 250 mm long solenoid wound with insulated copper wire and mounted on a base, with switch and 4mm terminals.
Operating voltage is 12 V A.C. or D.C. At 6A max.
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.
Consist of a closed transparent box with a transparent tube through the center.
The box contains iron filings and silicon oil.
When one or more cylindrical magnets are inserted into the central tube, the filings are attracted and line up along the field lines in all dimensions With Cylindrical Magnet.
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.
