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

Magnetism
Electromagnetic Field Apparatus
This apparatus demonstrates how current produces magnetic fields using three conductor setups: straight wire, single loop, and solenoid – mounted on a clear Perspex frame which enables it for overhead use for demonstration to a group of students.
Highlights:
- Supports up to 1 A current for visible field effects.
- Includes three compasses for field mapping.
- Ideal for teaching magnetic fields and hand rules with clear visibility.
- Includes Experimental manual to guide students.

Magnetism
Magnetic Field Demonstrator
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.
