1. What is Magnetic Susceptibility?

Magnetic susceptibility is a dimensionless proportionality constant that indicates the degree of magnetization of a material in response to an applied magnetic field. It quantifies how much a material will become magnetized in an external magnetic field.

2. How Does the Calculator Work?

The calculator uses the magnetic susceptibility formula:

Where:

• \( \chi \) — Magnetic susceptibility (H/m)
• \( I_{mag} \) — Intensity of magnetization (A/m)
• \( I \) — Magnetic field intensity (A/m)

Explanation: The formula calculates the magnetic susceptibility by dividing the intensity of magnetization by the magnetic field intensity.

3. Importance of Magnetic Susceptibility

Details: Magnetic susceptibility is crucial for characterizing materials' magnetic properties, classifying materials as diamagnetic, paramagnetic, or ferromagnetic, and in various applications including material science, geology, and medical diagnostics.

4. Using the Calculator

Tips: Enter intensity of magnetization and magnetic field intensity in A/m. Both values must be positive, and magnetic field intensity must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What are the typical values of magnetic susceptibility?
A: Magnetic susceptibility values vary widely: diamagnetic materials have small negative values, paramagnetic materials have small positive values, and ferromagnetic materials have large positive values.

Q2: Is magnetic susceptibility dimensionless?
A: While often treated as dimensionless in many contexts, magnetic susceptibility has units of H/m (henry per meter) in the SI system when calculated from the given formula.

Q3: How does temperature affect magnetic susceptibility?
A: For paramagnetic materials, susceptibility decreases with increasing temperature (Curie's law), while for diamagnetic materials, it's largely temperature-independent.

Q4: What's the difference between volume and mass susceptibility?
A: Volume susceptibility (as calculated here) is per unit volume, while mass susceptibility is per unit mass. Mass susceptibility = volume susceptibility / density.

Q5: Can this calculator be used for all materials?
A: This calculator uses the basic formula valid for linear magnetic materials. For ferromagnetic materials with nonlinear behavior, more complex models are needed.
