Tel tron Helmholtz Pair of Coils D

Tel tron Helmholtz Pair of Coils D

Product Code : JA-APE-7302

The Tel tron Helmholtz Pair of Coils D (SKU JA-APE-7302) is a pair of coils that produces a uniform magnetic field across the Tel tron D-series electron tubes. Supplied by JaincoLab, these Helmholtz coils for e/m and electron-beam experiments give a maximum field of about 10 mT, and they can be set up in the Helmholtz geometry or arranged so that the field is vertical or coaxial with respect to the tube axis.

Specifications

The coil pair provides the magnetic field for D-series tube experiments: in the Helmholtz geometry the field is uniform and perpendicular to the tube axis, and the maximum field is about 10 mT. Coil turns, current rating and dimensions are not listed and are confirmed on the quotation.

Applications of the Helmholtz coils for electron tubes

The coils supply the magnetic field needed in electron-beam experiments with the D-series tubes, such as bending the beam in the deflection and Perrin tubes, balancing electric and magnetic deflection to find e/m, and focusing the beam in the Maltese cross tube.

  • Magnetic deflection of the electron beam in the Tel tron Electron Deflection Tube D and Perrin Tube D
  • Field-balance measurements of the specific charge e/m and the electron velocity
  • Studying beam focusing with the Maltese Cross Tube D
  • Demonstrating the uniform field region of a Helmholtz arrangement in B.Sc and engineering physics labs

Scope of supply and ordering

The listing covers the Tel tron Helmholtz Pair of Coils D, that is, two coils. They fix to the Tel tron Tube Holder D, which has two base holes for them; the holder, the tubes and the coil power supply are separate. Accessories, spares and quantities are confirmed on the quotation.

Minimum order quantity, lead time and packing for the coils are confirmed on each quotation for the quantity and the delivery destination. Coils can be quoted singly with a tube, as sets for several benches, or for bulk college and tender orders, including export to Africa, the Middle East and South and South-East Asia.

Frequently asked questions

What field strength do the coils produce?
