Subtopic: Biot-Savart Law & Ampere's Circuital Law
Question Statement:
A piece of paraffin is placed in a uniform magnetic field Ho. The sample contains
hydrogen nuclei of mass mp. which interact only with external magnetic field. An
additional oscillating magnetic field is applied to observe resonance absorption. If gi
is the g-factor of the hydrogen nucleus, the frequency, at which resonance absorption
takes place, is given by
