Re: impedance of free space



Agreed - not a boo boo! I mis-read your Ke and Km as relative epsilon &
mu, respectively, instead of the coefficients in Coulomb's and the
Biot-Savart laws, respectively! (You gotta spell it out for us kids.)

Not a boo-boo because I didn't use mu and epsilon. K_e and K_m are
analogous to the gravitational constant G and have respective units:
Nm^2/C^2 and N/A^2.
