About This Product
Field lines around charged electrodes are hard to picture from textbook diagrams alone. Here the electrodes sit in a shallow clear dish, so the pattern can be watched at the bench or, with the unit placed on an overhead projector, shown to a whole room at once. Fine height adjustment at each terminal lets the teacher set the electrodes accurately before a demonstration. Schools and distributors in Turkmenistan, Antigua and Barbuda, Belgium, Bahrain, Guyana and Kyrgyzstan can order the Electric Fields Apparatus from School Educational Instrument.
