1. What is Magnetic Susceptibility?

Magnetic Susceptibility (χₘ) is a measure of the degree to which the magnetic moments of a material align with an applied magnetic field. It quantifies how easily a substance can be magnetized in the presence of a magnetic field.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \chi_m \) — Magnetic Susceptibility (H/m)
• \( \mu \) — Magnetic Permeability (H/m)

Explanation: This formula calculates the magnetic susceptibility by subtracting 1 from the magnetic permeability of the material.

3. Importance of Magnetic Susceptibility Calculation

Details: Magnetic susceptibility is crucial for understanding material properties in magnetic fields, designing electromagnetic devices, and studying material behavior in various scientific and engineering applications.

4. Using the Calculator

Tips: Enter magnetic permeability in H/m (Henry per meter). The value must be valid (permeability > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between magnetic susceptibility and permeability?
A: Magnetic susceptibility quantifies how much a material will become magnetized in an applied field, while permeability measures how easily magnetic field lines pass through a material.

Q2: What are typical values for magnetic susceptibility?
A: Values vary widely: diamagnetic materials have small negative values, paramagnetic materials have small positive values, and ferromagnetic materials have large positive values.

Q3: How is magnetic susceptibility measured experimentally?
A: Common methods include Gouy balance, Faraday balance, and vibrating sample magnetometry techniques.

Q4: What factors affect magnetic susceptibility?
A: Temperature, applied field strength, and material composition are key factors that influence magnetic susceptibility.

Q5: Why subtract 1 in the formula?
A: The subtraction of 1 accounts for the magnetic susceptibility of free space (vacuum), which has a permeability of μ₀ = 4π×10⁻⁷ H/m.
