Fig. 3 (b) shows how grounding a heatsink attenuates the …
However, shielding the outside can be accomplished by grounding the conductor. This allows charges to flow (from ground) onto the conductor, producing an electric field opposite to that of the charge inside the hollow conductor. The conductor then acts like an electrostatic shield … See more (1) Shielding the inside from the outside. It is well known that no electric fields exist inside a hollow conductor, even if there are charges present … See more The electrostatic detection probe in all of these experiments is either a tiny charged pith ball or an electrostatic "compass," both of which are … See more This sequence of demonstrations was conceived by Prof Peter Heller at Brandeis University and developed in collaboration with him.
