In this experiment, a Maxwell‘s Wheel rolls down a rail. A force measurement shows that while the wheel is moving, measured gravitational force of the wheel is slightly smaller compared to it‘s resting state. The explanation for this is the force distribution among the vertical acceleration (which is measurable) and the angular acceleration of the wheel.

Amperage conversion at a transformer

In this experiment, low amperage is applied to one side of a transformer, which consists of two coils with a different number of windings and an iron core, while a much higher amperage can be measured on the other side. This current is sufficient to melt a nail.

Induced voltage in a magnetic field

In this experiment, a conductor swing is set in motion within a magnetic field, and the voltage difference at it‘s ends is measured. The electrons in the conductor are shifted periodically due to the Lorentz force while the conductor swings. This works the other way round, too: By applying an electric current to the conductor, the swing is moved sideways.
Exploding wire

In this experiment, a capacitor and a thin wire are get short-circuited. The current flowing through the wire is strong enough to cause an explosion.
Two coupled pendulums

In this experiment the oscillation of a coupled pendulum can be investigated. The oscillation is measured and examined by using a Fourier transformation.
Standing wave

A rope, put under tension using a weight, is forced to 12 oscillate. The experiment is performed when different frequencies and weights are applied. This results in different harmonic oscillations.
High temperature super-conductor
2012-11-26
3:18
A high-temperature super-conductor is cooled down using liquid nitrogen. When reaching the critical temperature, a magnetic cube lying on top of the super-conductor begins to levitate.
Electron Beam Deflection

An electron beam may be observed inside a Teltron tube. Its direction is changed when modifying the external magnetic field. This forces the electrons on a circular track.
