e and m by Helical Method Solenoid Method Manufacturer,Supplier and Exporter in India
Product Code : JA-EMA-1066
The Jaincolab e/m by Helical Method (Solenoid Method) apparatus is used to measure the charge-to-mass ratio (e/m) of the electron by the helical (solenoid) method, and comprises three major parts built for this measurement. 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 set includes a standard solenoid of multi-turned layers fitted on a wooden base, a power supply for the cathode voltage to the CRT with a high-resistance voltmeter, and a separate solenoid supply with coarse and fine control arrangement, together with an ammeter to measure the current passing through the solenoid. The cathode ray tube is mounted to move inside the standard solenoid.
