The following is a sequence of experiments that can accompany a standard lecture on electromagnetic waves. The entire sequence is quite long and you may not want to do...
The behavior of a substance in a non-uniform magnetic field will depend upon whether it is ferromagnetic, paramagnetic or diamagnetic. Here we test different substances to see how they are influenced by a magnetic field.
We...
10 cm microwaves are used for the demonstration of travelling and standing waves, reflection, interference, refraction, diffraction, absorption, polarization, tunneling, and waveguides.
The following is a sequence of experiments that can...
When a magnetic field is applied perpendicular to a conductor carrying current, a potential difference is observed between points on opposite sides of the conductor. This happens because the magnetic field deflects the moving electrons...
A superconducting material in the presence of a magnetic field excludes that field from its interior. This is shown by levitating a magnet above a high temperature superconductor.
We have a 25mm disc of ceramic yttrium barium...
