e/m Apparatus Manufacturer,Supplier and Exporter in India
Product Code : JL-LE-10490
The e/m Apparatus (SKU JL-LE-10490, Cat. No. JSS-026/020) is used to find the charge-to-mass ratio of the electron. A fine electron beam forms inside a vacuum tube, and a pair of Helmholtz coils around it bends the beam into a circle. Low-pressure helium in the tube glows along the beam, and the orbit diameter is read on an internal glass scale. It is supplied by JaincoLab.
