Replace metal-type troughs with the polypropylene pneumatic trough.

Supplier: ELWE LEHRGERAETEBAU KLINGENTHA

Used e.g. to form homogeneous magnetic fields. Two identical coils placed in parallel by means of three fastening devices. The coils can be connected in series or in parallel. To determine e/m, the wire beam tube is placed between the Helmholtz coils in such a way that the visible beam is perpendicular to the homogeneous magnetic field. The generated magnetic field can be measured with a magnetic field meter with hall elements. Specifications.

Supplier: ELWE LEHRGERAETEBAU KLINGENTHA

Motor with rotor that lacks iron and thereby has a very low moment of inertia, which in turn enables fast start and stop or change of direction of rotation. The time from start to maximum speed (3000 rpm) is only 11 ms. Can be used for experiments with mechanical oscillations. The motor is most conveniently operated with a function generator.

Supplier: 3B Scientific

Digital counter/timer for measuring duration of motion, transition times, periods, pendulum periods, frequencies, as well as for counting events or Geiger tube pulses. Includes a speaker that can be turned on and off and power supplies for direct connection to photo gate or a Geiger-Müller counter.

Supplier: CORNELSEN EXPERIMENTA

Light plastic pendulum ball. Suitable for experiments with pressure waves with tambourine.

With the equipment, centrifugal forces that arise during a body's rotation around a specific axis can be measured and examined. The device consists of a plane with a path for a cart. On the underside there is a vertical shaft that is mounted in a bearing. The plane is made to rotate with a laboratory motor connected with a drive belt to the bearing. The experimental trolley is placed on the track and prevented from leaving the track by two bent steel wires. A wire is connected to the trolley that runs over a pulley and on to a dynamometer.

Supplier: 3B Scientific

Track with two trolleys and other accessories for investigating linear motion. The trolleys move with minimum friction on wheels with high-quality ball-bearings. They are fitted with magnets at their front ends for experiments involving both elastic and inelastic collisions.

With a few simple steps, the ballistic pendulum is quickly rebuilt into a throwing device with a variable/variable firing angle. The ballistic pendulum, a common method for determining the speed of a pistol bullet, is to push them into a sandbag. With the ballistic pendulum, a harmless variant of this experiment can be performed in the classroom.

The profile of the runway has been designed so that the experiments can be performed easily, quickly and safely. The length of the track (1,5 m) is more than sufficient for all conceivable physical experiments to be performed. The trolleys are equipped with overload protection in the form of a recessed, resilient wheel suspension. Characteristics.

Recipient with opening at the top. With the help of a rubber plug with electrical connection bushings, for example, a bell can be hung up in ordinary laboratory cables.

Supplier: PHYWE

Divers of glass, placed in a bottle filled with water. If the liquid pressure increases, water flows into the diver, whose average density increases. This results in the diver sinking to rise again towards the surface when the pressure is reduced.

Supplier: PHYWE

For demonstration of the rocket principle. The model is half filled with water and placed on a launch pad. An internal overpressure is inflated with an air pump. The rocket is released manually and then flies freely longer than 40 m. Can also be propelled with a carbon dioxide cartridge along a tensioned line. The rocket's traction force, with carbon dioxide cartridge as the driving source, can be measured with a dynamometer and amounts to about 0.3 N.

Coil springs made of spring steel. With stirrups at both ends. Suitable for Hook's team and swing attempts.

This experiment shows how fast a vertical pendulum would swing, if it was placed on a foreign celestial body e.g. the moon or March. Phywe's variable g-pendulum can change the plane of oscillation from the vertical, a=0°, up to the horizontal plane, ie a=90°. When a=0°, g acts at full force. If the plane of oscillation is not parallel to the vertical, only g × cos a acts on the pendulum motion. A movement to the moon shows that gravity amounts to about 16.6% of the earth's, which in our pendulum on the earth, corresponds to an angle α=80.5°. The force of attraction in March amounts to 38% of the earth, which can be simulated in the g-pendulum by setting a= 69°.
