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 field2. Determine e/m ratio of an electron and verify the polar coordinate equation of electron spiral motion.
3. Measure geomagnetic component.
