Enclosed to prevent air currents from affecting the deflection of leaves. Each leaf is suspended from two small hooks. The leaves pivot, rather than bend, when charged. The front and rear side of the box is made of square glass to allow visibility. supplied with a booklet of 6 leaves.
A pair of light weight balls are suspended from a rod with a piece of string. The support rod is mounted on an insulated base. Provides a simple yet effective way to learn about electrostatics.
Flask type, conical flask with rubber stopper which holds a metal rod with disc top and lower flat end to which a leaf may be pasted. Supplied with a booklet of 6 leaves and instructions for fitting.
Materials for demonstrating the generation of electrostatic charges with friction rod . a hollow glass rods Kit includes solid glass rod and a wool friction hard rubber rod, silk friction pad, pad, flannel friction pad, animal fur( synthetic) friction pad, 3 balloons, 10 ft of string and instructions. Grades 9+
The charge is indicated by the deflection of an aluminized plastic straw which rotates freely on the saddle of the conducting rod. A scale on the instrument’s back is graduated in degrees to allow measurement of the deflection. The conducting rod is recessed in the metal housing to shield against air currents. With replacements aluminized straws.
A small but powerful van de Graaff generator. Generates high potential (up to 200 KV) and sparks up to 3″. With aluminum dome (7″ dia) and discharge sphere (4″ dia). The total height is about 18″. Comes with one replacement belt and standard accessories.
A simple hand driven van de Graaff generator for producing very high electric potentials at low currents. The apparatus consist of a wooden base, insulated Perspex stand, rubber belt, removable metal dome (135 mm dia), a driving wheel and driving belt. The discharge sphere (50 mm dia) is mounted on a pivoted arm, with handle for adjustment. The length of…
Traditional Electrostatic generator consists of two 250mm diam. Discs with radial aluminum segments driven in opposite directions by hand wheel and belt, with two Leyden jars, on wooden base.
