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
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.

Electromagnetic Induction Demonstrator
Electromagnetic Induction Demonstrator kit is used for demonstrating the important experiments performed by Faraday and how they lead to some of the significant conclusions in electromagnetism. It is designed to perform studies even beyond the basic experiments. It comprises of three solenoids of 20, 40 and 80 turns, each of identical cross-sections, mounted on a transparent base along with a milliammeter. These three coils of different lengths are provided to understand the effect of length of coil on induced current. Repeatedly inserting a magnet into the coil and removing it causes electric current to flow through the coil, which can be read directly from the milliammeter. Also notice that the milliammeter shows zero current when the magnet is not moving. Using this apparatus, students can study correlations between induced current to that of magnetic field strength, number of turns of coil, magnetic field polarity and speed. Requires 1.5V dry cell battery (not included).
