In Paramagnetic oxygen analyzer, the expression for magnitude of force produced can be expressed as, F = C (K-KO), where K= magnetic susceptibility of surrounding gas and KO= magnetic susceptibility of sphere. C denotes which of the following?
(a) Magnetic field strength
(b) Magnetic gradient
(c) Function of magnetic field strength and gradient
(d) Magnetic flux
This question was addressed to me during an interview for a job.
My doubt stems from Paramagnetic Oxygen Analyser topic in division Industrial Gas Analysers of Analytical Instrumentation
