Leslie’s Cube
Catalogue No: 1061080/1
Useful for qualitative activities in thermal radiation. The results can also be quantified using a suitable radiation sensor facilitating investigation of emission and absorption of radiation from different surfaces at a same temperature or radiation from a single surface at different temperatures (Stefan-Boltzman’s Law). Comprises a sheet metal cube of sides about 130mm with opening at the top for pouring in water and inserting a thermometer through a holed rubber stopper. Each of the four vertical faces is finished black, varnished, roughened and polished.

Magnetic Field Chamber
Catalogue No: 1070380/1
Demonstrates three-dimensional nature of magnetic field associated with cylindrical magnets. Comprises a hollow chamber of clear acrylic with a tunnel at its center to hold cylindrical magnets. The chamber has high quality iron filings, which aligns itself as per the magnetic field geometry of the magnet. Also allows magnets of other shapes to be investigated by simple positioning their poles adjacent to any side of the chamber.
