Magnetic Constant

magnetic constant

[mag′ned·ik ′kän·stənt] (electromagnetism) The absolute permeability of empty space, equal to 1 electromagnetic unit in the centimeter-gram-second system, and to 4π × 10^-7 henry per meter or, numerically, to 1.25664 × 10^-6 henry per meter in the International System of units. Symbolized μ₀.

Magnetic Constant

a proportionality constant μ₀ which occurs in a number of formulas involving magnetism when they are written in rationalized form (in the International System of Units). Thus, the induction B and intensity H of a magnetic field are related in a vacuum by the formula B = μ_oH, where μ₀ = 4π ×10^-7 henry sperm (H/m) ≈ 1.26 ×10^-6 H/m.
