Tel tron Helmholtz Pair of Coils S
Product Code : JA-APE-7303
The Tel tron Helmholtz Pair of Coils S (SKU JA-APE-7303) supplies the magnetic field for experiments with the Tel tron Student-series electron tubes. Supplied by JaincoLab, this Helmholtz coil pair for S-series tubes produces a uniform field perpendicular to the tube axis, with a maximum of about 10 mT, and on the Tube Holder S the coils can be placed in the Helmholtz geometry or at other distances to give vertical or coaxial fields.
Specifications
The two coils sit in the slots of the Tel tron Tube Holder S, whose metric rulings allow spacings of up to 150 mm; in the Helmholtz position they give a uniform field across the tube, with a maximum field strength of about 10 mT. Current rating and coil dimensions are confirmed on the quotation.

Uses of the Helmholtz coils for S-series tubes
In student practicals the coils provide the magnetic field that bends or focuses the electron beam in S-series tubes; with the Dual Beam Tube S, for example, a field at right angles turns the beam into a circle for e/m measurement.
- Circular-beam e/m measurement with the Tel tron Dual Beam Tube S
- Coaxial-field experiments on electron collisions with the axial gun of the Dual Beam Tube S
- Comparing the field at Helmholtz spacing with the field at other coil spacings
- Magnetic-field topics in B.Sc and engineering physics laboratory courses
