Wool and the short, yellow PVC pipe are a good combination: put the wool in one pot and stir/rub the PVC pipe against the wool. Then remove the PVC pipe…

This demonstration illustrates how an electroscope can be charged using electrostatic charges generated via friction.

This demonstration showcases the principles of electrostatic induction by generating high-voltage sparks and charges, illustrating concepts of electrical potential and charge separation.

This demonstration is an entertaining visualization of the induction of charges and its repelling effect due to opposite values.

With this demonstration we can better visualize how the faraday’s cage works and why it works.

This demonstration showcases that Faraday’s cage can block external static and non-static electric fields. It illustrates that electromagnetic waves, which include radio waves, cannot penetrate the cage. This demonstration provides…

This demonstration illustrates the electric field lines inside and around the capacitor.

This demonstration shows how the Leyden jar can store electrical charge, which can then be discharged in a visible spark. The dramatic discharge of a spark can engage audiences and…

This demonstration illustrates how capacitors work under various conditions and parameters.

This demonstration illustrates the temperature dependence of resistance. The effect is caused by the fact that the electrons moving through the wire collide with vibrations (phonons) created in the material…

This demonstration demonstrates the Thermo-Electric effect and the conversion from heat energy into electrical energy and then into mechanical energy. It also demonstrates “useful energy”: the total heat energy is…

This experiment demonstrates how a flowing current through a wire generates a magnetic field by putting a needle next to it.

This demonstration shows the magnetic field around a magnet using iron filings.

This demonstration showcases the connection between electricity and magnetism by providing an insight into the behavior of wires under electric current and influence of the magnetic field of each of…

With this demonstration, one can clearly show how coils and magnets interact together and produce an electrical current.

This demonstration illustrates magnetic braking via Eddy currents as the pendulum is stopped when the circuit is completed.

This demonstration illustrates Lenz’s law, as the EMF induced in the ring counteracts the magnetic field from the electromagnet, and ejects it upwards.

This demonstration shows the behavior of sunset through Rayleigh scattering. It is a clear way to demonstrate the behavior of light in the atmosphere and gain student’s interest.

The two polarizer setup filters vertically and horizontally, so no light gets through. By adding a third one one in between, a superposition of vertical and horizontal polarization is induced…

This demonstration illustrates absorption and fluorescence of differently coloured materials using UV light. It is also suitable for demonstrating scintillate materials and their working principle. One of the electroscopes in…
