LC circuit in external static magnetic field

In summary, placing an LC circuit in a steady magnetic field may initially experience changes due to Lenz's Law, but at very low temperatures, the presence of a paramagnet in the inductor may alter the susceptibility and impact the induction and resonance of the circuit. This possibility is supported by the concept of paramagnetism, which refers to the tendency of certain materials to become magnetized in the presence of an external magnetic field.

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?

Related to LC circuit in external static magnetic field

1. What is an LC circuit in an external static magnetic field?

An LC circuit in an external static magnetic field is a type of electrical circuit that consists of an inductor (L) and a capacitor (C) connected in series. The circuit is placed in an external magnetic field, which causes a change in the inductance of the circuit and induces a current within it.

2. How does an LC circuit behave in an external static magnetic field?

The behavior of an LC circuit in an external static magnetic field is dependent on the strength and direction of the magnetic field. When the magnetic field is applied, it causes a change in the inductance of the circuit, which results in a change in the current flow within the circuit.

3. What is the purpose of using an LC circuit in an external static magnetic field?

The main purpose of using an LC circuit in an external static magnetic field is to study the behavior and effects of magnetic fields on electrical circuits. This type of circuit can also be used in various applications, such as inductance-based sensors and filters.

4. What factors affect the behavior of an LC circuit in an external static magnetic field?

The behavior of an LC circuit in an external static magnetic field is affected by several factors, including the strength and direction of the magnetic field, the values of inductance and capacitance in the circuit, and the frequency of the applied voltage. Any changes in these factors can alter the behavior of the circuit.

5. How is the resonance frequency of an LC circuit affected by an external static magnetic field?

An external static magnetic field can affect the resonance frequency of an LC circuit by changing the inductance of the circuit. As the magnetic field increases, the inductance also increases, resulting in a decrease in the resonance frequency. Conversely, a decrease in the magnetic field would lead to a decrease in inductance and an increase in resonance frequency.
