How It Is Used
The coils are positioned around a D-series tube so that it sits in the uniform field between them. Passing a current through the pair bends the electron beam for magnetic deflection, dual-beam and e/m experiments.
Frequently Asked Questions
What field strength does the Teltron Helmholtz Pair of Coils D reach?
The maximum field is about 10 mT, approximately 300 times weaker than the ~3 T of an MRI machine.
