Bar Magnet Alnico (Pair) Size are mentions below which we have :- 38 x 10 x 5 mm (1.5") 50 x 10 x 5 mm (2") 75 x 10 x 5 mm (3") 100 x 10 x 5 mm (4") 150 x 10 x 5 mm (6")

Barlow Wheel

Description

This apparatus spins an electrically charged brass wheel spin, without the aid of a motor. When the wheel electrified by a voltage source (battery), the slotted brass disc sets up eddy currents throughout the structure. This electricity is then attracted to 4 strong neodymium magnets, causing the wheel to spin.

Floating Magnet Set

Description

Demonstrate laws of magnetic attraction and repulsion. Consists of a stand with 5 magnetic rings sealed in plastic case to reduce wear and breakage.

Force on a Conductor Balance

Description

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

Description

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.
