Supplier: CORNELSEN EXPERIMENTA

72 series-connected semiconductor elements, mounted between two ceramic plates which in turn are attached to heat-conducting metal. If the metals are exposed to different temperatures, a voltage arises, sufficient to drive, for example, a slightly rotating motor. The thermogenerator can also be run in the other direction, ie. a voltage is connected and a temperature difference is obtained across the metal legs.

Supplier: PHYWE

Precision capacitor for electrostatic tests e.g. examination of the relationship between charge, voltage and capacitance. Measurement of the dielectric constant and the electrostatic induction constant. The permanently mounted plate is well insulated while the movable plate is mounted directly in the stand. The distance between the capacitor plates can be adjusted with an accuracy of 0.1 mm. Distance between plates 0 to 70 mm.

Supplier: PHYWE

TESS OE3 contains 19 components. With TESS OE3 as a complement to TESS OE1 and OE2, another 30 experiments can be performed in the field of wave optics. Delivered in a plywood box.

Supplier: 3B Scientific

Photographic diffraction objects in slide frames.

Supplier: CORNELSEN EXPERIMENTA

Used for electrostatic experiments.

Supplier: PHYWE

Apparatus for demonstrating the independence of the components of a composite motion. A force is exerted against an arrow, in the direction of a vertically set target, by means of a wire connected to an elastic band. When the arrow is released, the target is released at the same time. The arrow always hits the free-falling target, regardless of the position from which the arrow is released. Supplied with wooden plate with mounted strap, spring lock for attaching the target, arrow with string (approx. 275 cm) and target.

Supplier: CORNELSEN EXPERIMENTA

Consists of a ball with check valve, vent valve and suspension hook. For use in conjunction with an electronic scale (0,001 g).

Supplier: CORNELSEN EXPERIMENTA

Consists of a plastic cylinder placed on an insulating rod between two tip electrodes. When connecting a high-voltage source, a charge transport is obtained which causes the cylinder to rotate.

Supplier: CORNELSEN EXPERIMENTA

Used to detect electric charge. Also suitable for use with belt generator and Faraday's cage. Equipped with connection for 4 mm banana plug.

Supplier: PHYWE

The following experiments can be performed.

Supplier: PHYWE

Suitable for use as pendulum bobs for frequency experiments. Hardened and polished ball bearings with eyelet.

Supplier: CORNELSEN EXPERIMENTA

For charging attempts. About 50 pcs in a box.

Supplier: CORNELSEN EXPERIMENTA

For storage of electric charge. Consists of a glass cylinder with metal foil and a conductor ball on a rod.

Supplier: PHYWE

Used in studies of the power action of a current-carrying conductor in a magnetic field. The field can e.g. obtained from U-magnet 765-0444. With two bands, the force action between these at different current directions can be investigated. Each band is provided at both ends with a 4 mm banana plug.

Supplier: PHYWE

With equipment, demonstration and accurate calculations can be performed of how the atom's spectral lines are divided by the influence of a magnetic field (the Zeeman effect).

Supplier: GR NNA PLASTEMBALLAGE AB

For use in, for example, examination and determination of resistivity.
