With this kit students can map both the potentials and the electric fields around any conceivable system of two-dimensional charged conductors.
The procedure is simple:
- Draw Any Electrode — Draw the electrode with the special, conductive silver ink pen. It is easy to use, it dries quickly and there is no mess.
- Plot the Equipotentials — Connect a battery or power supply across the electrodes, then use a voltmeter to locate the equipotential lines.
- Plot the Electric Field — Tape voltmeter probes together, then hold one probe on the paper and rotate the other probe around it like a compass. The maximum voltage reading indicates the direction of the electric field.
