1. The problem statement, all variables and given/known data What effect would placing an LC circuit in a steady magnetic field have have on its resonant frequency? The inductor contains a paramagnet. This is asked about at very low temperature. 2. Relevant equations 3. The attempt at a solution Apart from initial changes due to Lenz's Law when the field is switched on I can't see what effect it would have. At a very low temperature is it possible to saturate the paramagnet, altering the susceptibility and thus the induction and resonance?
