Helmholtz Coils, 300 mm | Electron Tubes | Electricity and Magnetism

Helmholtz Coil Pair,
300 mm Diameter

Description
Experiments

Applications and Experiments:_..

These Helmholtz coils are essential components for determining the specific charge of an electron (e/m) using a fine beam tube (item no. 8000667 / 8000668). In addition, when combined with the rotating induction coil (item no. 1013131), the Helmholtz coils can be used in experiments investigating induction.

Product Information:_..

The pair of Helmholtz coils is used to generate a homogeneous magnetic field. The coils can be connected in parallel or connected in series.
A retaining spring clip mounted on the upper spacer bar is used to secure the Hall sensor for measuring the magnetic field.
