WebMay 7, 2016 · If we take out the 2π and h, we get this simple equation: 0 = r2 + r −A We know that 2π, h, and A are constants, so what we have here is a quadratic equation of the form 0 = ar2 + br + c. In our case, a = 2π, b = 2πh, and c = A. We can solve for r using the quadratic formula: r = −b ± √b2 −4ac 2a WebThe value of mu naught (µ 0) or the value of absolute permeability of free space had the exact defined value until 20 May 2024.
