Calculate magnetic permeability and classify materials based on their magnetic properties.
Determine the magnetic permeability (μ) of materials by analyzing the relationship between magnetic flux density (B) and magnetic field intensity (H). Classify materials as diamagnetic, paramagnetic, or ferromagnetic.
