Mass Of Electron Apparatus Kit Manufacturer,Supplier and Exporter in India
Product Code : EL-P-10783
Quick Answer: The Mass Of Electron Apparatus Kit is a magic eye tube mounted on a base with terminals for heater and plate voltages. An air cored solenoid placed over the tube curves the fan of electrons seen through the end of the tube, and this curvature is measured to calculate the approximate mass of an electron.

About This Product
This experiment is a school-level way of finding the mass of the electron. Electrons leave the heated cathode and form a visible fan on the tube. When a current passes through the solenoid, its magnetic field bends the paths of the electrons, because a moving charge feels a force at right angles to its motion. Students measure how much the fan curves and, with the known charge of the electron, estimate its mass. The result is approximate. Alongside supply within India, the Mass Of Electron Apparatus Kit is offered for export to Peru, Chad, Grenada, Gabon, Yemen and Georgia.
Frequently Asked Questions
Q1. What does the Mass Of Electron Apparatus Kit do?
It lets students see a fan of electrons in a magic eye tube, curve it with a solenoid and measure the curvature to calculate the approximate mass of an electron.
Q2. What connections does the base have?
The base has terminals to accept both heater and plate voltages.
Q3. How is the field produced?
An air cored solenoid is placed over the tube and a current is passed through it. The field at the centre of the solenoid curves the fan.
