About Magnetic Reluctance Units

Common Magnetic Reluctance Conversions

• 1 A/Wb = 1 H^-1 (magnetic reluctance = inverse inductance for a 1-turn circuit)
• 1 kA/Wb = 10³ A/Wb = 10³ H^-1
• 1 MA/Wb = 10⁶ A/Wb (typical SMPS ferrite core reluctance)
• 1 Gb/Mx ≈ 7.9577 × 10⁷ A/Wb = 10⁹/(4π) A/Wb (CGS unit)
• N-turn coil with inductance L: ℛ = N² / L (in A/Wb)
• Air gap (length l, area A): ℛ = l / (µ₀ A) ≈ l / (1.257 × 10^-6 A) A/Wb
• Ferrite E-core (100 kHz SMPS): ℛ ≈ 1-50 MA/Wb
• 0.1 mm air gap, 1 mm² cross-section: ℛ ≈ 80 GA/Wb
