SHADOW EFFECT TUBE, ELECTROMAGNET (0642)
Demonstrates that cathode rays travel in straight line and cast shadows. An object obstructing cathode rays casts its shadow on the fluorescent wall facing it, and if the running cathode rays are subjected to magnetic effects, per an electromagnet, the shadow is affected by its slight rotation change. Complete with electromagnet.
