Tangent Galvanometer
Supertek tangent galvanometer is used to investigate the magnitude and direction of the magnetic field produced by a current carrying conductor.The apparatus may also be used to determine the magnitude and direction of the horizontal component of the earth’s magnetic field. In this tangent galvanometer, 305 cm of wire is wound on the nonmagnetic stand, which is of sturdy design. 4mm sockets are provided for the input. Supplied with user manual.

Tangent Galvanometer
Investigate magnetic fields produced by an electric current. Students observe as a current carrying coiled wire produces a magnetic field perpendicular to the direction of the current. Students learn that the strength of the magnetic field varies with the number of times the wire is coiled and voltage applied across the coils. Complete instructions provided.

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

Faraday’s Disc
To demonstrate conversion of mechanical energy into electrical energy. A copper disc with a turning handle rotates between two poles of a horse shoe magnet. On base with two terminals, one of which is connected to a pillar supporting the disc and the other to a brush bearing on edge of the disc.

Racing Rings
Racing Rings consists of three rods one each of copper, aluminum and PVC. When ring magnet is dropped down the PVC rod, it falls unobstructed. When the rings are sent down either of the metal rods, they experience a slower fall. The two metal rods create an induced magnetic field to that adds resistance to the rings’ travel. Since the metals are different, they fall at different rates.

Electromagnetic Field Demonstrator
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 5 A. With the included iron filings and 8 magnetic compasses, you can investigate the associated field and flux patterns.
