LC circuit in external static magnetic field

Click For Summary
SUMMARY

Placing an LC circuit containing a paramagnet in a steady magnetic field affects its resonant frequency, particularly at very low temperatures. The initial changes due to Lenz's Law occur when the magnetic field is activated. At low temperatures, saturation of the paramagnet can alter its susceptibility, which in turn modifies the inductance and resonance of the circuit. Understanding these effects is crucial for precise applications in low-temperature physics.

PREREQUISITES
  • Understanding of LC circuit theory
  • Knowledge of Lenz's Law

Homework Statement


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.

Homework Equations

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?
