How does shielding work? Is it a two-way street and work both ways? Can electric fields not penetrate metals? What's going on? This sequence of demonstrations addresses these questions.... Read more about Electrostatic Shielding
A 60 Hz AC magnetic flux from an iron core induces an emf in a suspended coil of wire. With appropriate capacitance added, the coil will be attracted to, repelled from, or not affected by the magnetic flux.
10 cm microwaves are used for the demonstration of travelling and standing waves, reflection, interference, refraction, diffraction, absorption, polarization, tunneling, and waveguides.
