Quick Answer:The Teltron Helmholtz Pair of Coils S generates a uniform magnetic field perpendicular to the axis of a Teltron S-series tube, reaching a maximum of about 10 mT. Instructions are included.
Last updated: 18 October 2026
Key Features
Uniform magnetic field across Teltron S-series tubes.
With the Teltron Tube Holder S, the coils can be set in Helmholtz geometry or at variable distances.
Field can be aligned vertically or coaxially with respect to the tube axis.
Maximum field strength about 10 mT, roughly 300 times weaker than the ~3 T of an MRI machine.
Instructions included.

How It Is Used
The coils are placed either side of an S-series tube on the tube holder. Current through them sets up a uniform field that bends the electron beam, as needed for magnetic deflection and e/m measurements.
