Heat Conductivity Bar Set
A simple, effective apparatus demonstrates the heat conductivity of various metals. Four metals bars (Copper, Aluminum, Brass and Steel) are mounted on a base with a hole for suspension. Every metal bar has same cross-sectional area and its conductivity value is marked on the back of the base. The sensitive temperature indicators are attached to the front of each of the four metal bars. The color of the temperature indicator changes with the change in temperature. Place the bars in a beaker of hot water and compare their relative conductivities. With instructions.

Helmholtz Coil
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 Supertek 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.
