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.

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.
-
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.

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.

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.
-
In this experiment the oscillation of a coupled pendulum can be investigated. The oscillation is measured and examined by using a Fourier transformation.
-
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.
-
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.
-
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.
-
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.
-
Cooling down a hot metal rod results in contraction of the rod. Resulting forces can be observed in this experiment.
-
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.
-
The experimental set up consists of five small vehicles which are coupled by springs. For this system, five different eigen modes may be found.
-
In this experiment the elastic and inelastic impact of a trolly can be investigated.
-
There is no possibility of canceling an irreversible process and at the same time of carrying all aids back to its starting situation.
-
In this experiment we observe simultaneously the trajectory of a projectile and a free falling object in the gravity field.
-
The experimental set up consists of five small vehicles which are coupled by springs. To observe the superposition of oscillations, the pendulum is forced to random oscillation. Using Fourier transformation, it may be seen that this oscillation is a superposition of five frequencies.
