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.
To demonstrate that when a current is passed through a conductor in a magnetic field, it is subjected to attraction or repulsion depending upon the direction of current in it.
The apparatus consists of a plastic base 160 x 140 mm on which two contact pillars are mounted.
Each pillar is provided with an external circuit.
A balanced beam is supported by the pillars on two bearings which form the fulcrum.
Two screwed masses are provided in the beam system, one moving vertically for the adjustment of sensitivity and the other moving horizontally for the adjustment of the equilibrium position, when no current is flowing.
Scale marked 0 to 75 x 1 mm, rider of 1 gm. weight with instruction manual.
Helmholtz Coils are a special arrangement of coils that are placed in such a way as to generate a very uniform magnetic field between them when a current is applied.
The strength of the magnetic field is proportional to the number of turns in the coils and the current applied to them.
The Helmholtz Coils setup consists of two field coils mounted on a track to provide a uniform magnetic field between the coils.
The proper separation for Helmholtz coils is marked on the track.
A pair of precision coils and 400 turns of wire are wound on heat resistant former of about 150 mm diameter.
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.
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 demonstrates the magnetic field patterns associated with the different shapes of current carrying conductors.
Comprises three conductors, each of different shape/configuration – straight rectangular, circular loop and solenoid all mounted on a plastic base.
Each configuration is provided with a pair of 4 mm sockets to connect them to a low voltage DC power source, with output current not exceeding 5A With the included iron filings and 8 magnetic compasses, you can investigate the associated field and flux patterns.
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.
