1.	In Paramagnetic oxygen analyzer, the electrostatic force that is exerted should have which of the following features?(a) It should be greater than the magnetic field and must be in the same direction(b) It should be equal to the magnetic field and must be in the same direction(c) It should be greater than the magnetic field and must be in the opposite direction(d) It should be equal to the magnetic field and must be in the opposite directionI had been asked this question during an interview.This is a very interesting question from Paramagnetic Oxygen Analyser in section Industrial Gas Analysers of Analytical Instrumentation
Answer» Right option is (d) It should be equal to the magnetic field and MUST be in the OPPOSITE DIRECTION The best explanation: The electrostatic FORCE that is exerted should be equal to the magnetic field and must be in the opposite direction. It is exerted by two charged vanes.
