Physics - What is the value of μ-naught in the Biot-Savart Law?
I'm trying to do my homework, but I can't find out where this μ-naught is coming from in the equations.
I googled it, and found 4.7e-7, but that didn't work with the equation. I know the equation's right because I got it from my prof and my TA.
Any input will help.. I'm terrible with physics.
