Utilize our free Magnetic Resistance Calculator to quickly determine the reluctance of a magnetic circuit. Input parameters like path length, cross-sectional area, and relative permeability to get precise results. Essential for engineers and students analyzing magnetic fields and circuit designs.
Formula:
The formula for Magnetic Resistance (Reluctance) is:
R = l / (μ * A)
- R = Magnetic Resistance (Reluctance) in Ampere-turns per Weber (At/Wb)
- l = Length of the magnetic path in meters (m)
- μ = Permeability of the material in Henrys per meter (H/m)
- A = Cross-sectional area of the magnetic path in square meters (m2)
Where μ = μ₀ * μᵣ
- μ₀ = Permeability of free space (approximately 4π × 10⁻⁷ H/m)
- μᵣ = Relative permeability of the material (dimensionless)
