China Wholesale Planck Constant Factory – LADP-14 Determining Specific Charge of Electron – Advanced Model – Labor
China Wholesale Planck Constant Factory – LADP-14 Determining Specific Charge of Electron – Advanced Model – Labor Detail:
Experiments
1. Quantitatively measure the rules of electron movement in both electric and magnetic field.
a) Electrical deflection: electron + transversal electric field
b) Electrical focusing: electron + longitudinal electric field
c) Magnetic deflection: electron + transversal magnetic field
d) Spiral motion magnetic focusing: electron + longitudinal magnetic field
2. Determine e/m ratio of an electron and verify the polar coordinate equation of electron spiral motion.
3. Measure geomagnetic component.
