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.

Amperage conversion at a transformer

In this experiment, low voltage 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 voltage can be measured on the other side.

Voltage conversion at a transformer

In this experiment, an oil dabbed cotton wool within an airtight test tube ignites because of heat produced by the adiabatic process running while compressing the air.

Pneumatic Lighter

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.

Maxwell‘s Wheel

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.

Induced voltage in a magnetic field

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.

Exploding wire

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

Two coupled pendulums

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.

Standing wave

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.

High temperature super-conductor

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.

Electron Beam Deflection

To observe the thermal length variation of different materials, hot steam is lead through tubes to heat them up. By using a heat dilatometer the thermal expansion of the tubes is measured.

The volume of a tube is expanded stepwise, keeping the temperature constant. In a pV diagram, pressure is depicted as a function of volume.

Boyle-Mariotte Law

Cooling down a hot metal rod results in contraction of the rod. Resulting forces can be observed in this experiment.

Bolt demolition

When a bi-metal coil is heated, both metals expand at different velocities, resulting in an unrolling of the coil.

To avoid heat exchange of a system, the volume of a glass tube has to be changed rapidly. Volume and pressure are depicted within a pV diagram.
