About This Product
These coils set up a homogeneous magnetic field between them and, together with the dual-beam tube, are used to determine the specific charge of the electron, e/m. They can be wired in parallel or in series to suit the experiment. During measurements of the field, a Hall sensor is held in a spring clip on the top crossbar. The Helmholtz Coils for Use with Fine Beam Tube is available for export to Zambia, Yemen, Madagascar, North Macedonia, Kuwait and Mozambique.
