Magnetic Materials & Boundary Conditions for B and H
Inside this lesson
- Classify materials as diamagnetic, paramagnetic, or ferromagnetic based on their relative permeability μᵣ
- Apply the constitutive relation B = μ₀μᵣH = μH to compute B from H in a magnetic material
- State and apply the magnetic boundary conditions: B₁ₙ = B₂ₙ and H₁ₜ = H₂ₜ (no free surface current)
- Recognize the analogy between magnetic and electrostatic boundary conditions
