Permeability of free space (mu_0):

1.2566e-6 T*m/A = 4*pi*10^-7 T*m/A

Magnetic field calculations for different current-carrying conductor geometries using the Biot-Savart law and Ampere's law.

Straight Wire: B = mu_0 * I / (2*pi*r)

Solenoid: B = mu_0 * n * I

Circular Loop: B = mu_0 * N * I / (2*R)

mu_0 = 4*pi*10^-7 T*m/A
