3B Scientific, UE3070700-115, Experiment for Electricity: Fine-Beam Tube, 115 V, 50/60 Hz
UE3070700-115 Includes Only:
- Fine Beam Tube on Connection Base R
- Helmholtz Coils, 300 mm
- DC Power Supply 0-500 V (115 V, 50/60 Hz)
- Analogue Multimeter ESCOLA 100
- Set of 15 Safety Experiment Leads, 75 cm
Features:
In the fine-beam tube, the path of electrons in a uniform magnetic field can be observed as a clearly delineated ray. This means that the radius of the circular path can be directly measured with a simple ruler. From the path radius r, the magnetic field B and the electron gun's accelerating voltage U the specific charge of an electron e/m can be calculated.
