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.

Educational Materials, Waves and Oscillations, Application: Physics, Chladni plate, circular, steel, Ø=240 mm

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: 3B Scientific

Highly evacuated electron tube with focusing electron gun and fluorescent screen (90×60 mm) inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using an optional Helmholtz coil pair D. By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge e/m and the velocity of the electrons.

A fog chamber from the well-known physics company PHYWE is the given focus of many exhibitions. Every day, thousands of visitors to technical museums, art museums, nuclear power plant information centers, universities and colleges are fascinated by these fog chambers that make the invisible background radiation visible. PHYWE has been developing and manufacturing these unique devices for more than 20 years. In total, there are more than 200 in operation in more than 40 countries. The fog chamber makes the invisible visible. Every second you can observe a large number of traces that originate from both cosmic radiation and the earth's natural radioactivity. The appearance of the trace immediately reveals the type of particle that has just passed. During normal operation, no additional preparation is used. If you want to increase the activity in the surface, you can blow in a thorium isotope.
