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.
-
Voltage 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.
-
Pneumatic Lighter
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.
-
Maxwell‘s Wheel
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…

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...
-
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
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.
-
Dilatometer
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.
-
Boyle-Mariotte Law
The volume of a tube is expanded stepwise, keeping the temperature constant. In a pV diagram, pressure is depicted as a function of volume.
-
Bolt demolition
Cooling down a hot metal rod results in contraction of the rod. Resulting forces can be observed in this experiment.
-
Bi-metal coil
When a bi-metal coil is heated, both metals expand at different velocities, resulting in an unrolling of the coil.
-
Adiabatic Process
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.
-
Five Coupled Pendulums
The experimental set up consists of five small vehicles which are coupled by springs. For this system, five different eigen modes may be found.
-
Momentum transfer
In this experiment the elastic and inelastic impact of a trolly can be investigated.
-
Irreversibility
There is no possibility of canceling an irreversible process and at the same time of carrying all aids back to its starting situation.
-
Monkey shot
In this experiment we observe simultaneously the trajectory of a projectile and a free falling object in the gravity field.
-
Superposition
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.
-
Parallel Plate Capacitor
The plate distance of a parallel-plate capacitor is changed and its influence on charge and voltage is measured. The influence of a dielectric medium on charge and voltage is shown.
-
Pulling Test
A wire is extended at a constant velocity. Occurring forces are measured, so that the Young's modulus can be determined.
