    Constants

    Permeability of free space (μ₀):

    1.2566e-6 T·m/A = 4π×10⁻⁷ T·m/A

    Formulas

    Straight Wire: B = μ₀I / (2πr)
    Solenoid: B = μ₀nI
    Circular Loop: B = μ₀NI / (2R)
    μ₀ = 4π×10⁻⁷ T·m/A

    About Magnetic Field Calculator

    Calculate magnetic field strength for different current-carrying conductor geometries using the Biot-Savart law and Ampère's law.

    Configurations

    • Straight Wire: Field decreases with distance, forms concentric circles
    • Solenoid: Creates uniform field inside the coil
    • Circular Loop: Field strongest at center, perpendicular to loop plane

    Applications

    • Electromagnet design
    • MRI machines and particle accelerators
    • Electric motors and generators
