A05-4065 Newton Meter GN-1

●Replaces traditional "Van de Graaff” generators. ●Allows any experiment on static electricity to be performed in classroom much easier and less costly. ●Easy to realize that there is no motor and no battery generating static electricity because of its transparent body. ●Easy to understand that friction between two different materials can generate static electricity (positive and negative charge). ●Works well even in high humid and hot conditions.
