e and m By Thomson Bar Magnet Method Manufacturer,Supplier and Exporter in India
Product Code : JA-EMA-1065
The Jaincolab e/m by Thomson Bar Magnet Method apparatus is used to measure the charge-to-mass ratio (e/m) of the electron by the Thomson bar-magnet method, demonstrating the controlled bending of a stream of high-speed electrons in a magnetic field. As a manufacturer and exporter of Scientific Instrument equipment based in Ambala, Haryana, Jaincolab supplies this e/m apparatus to educational and industrial laboratories across India.
The actual measurement of the ratio of the electron's charge to its minute mass gives students a genuine sense of experimental achievement. This e/m apparatus has been perfected so that this fundamentally important measurement can be carried out with good accuracy.
