 inductance i ran across a formula and i would like to know what all of the variables are: L = [(N^2) * μ * A] / l im pretty sure l is length and A is area but i am confused about the rest. any thoughts? | |

| L = [(N^2) * μ * A] / l that is what i saw from you.. there are 2 formulas for L (inductance), one is given n (number of turns per unit length), and one is given total N (total number of turns) A is the cross sectional area of the coil l is the length of the coil hope that helps. david

| that jumbled part was supposed to be the greek symbol mu. like 10^-6 maybe? | |

| AL ( I can't subscript the 'L') might also be a factor that is supplied by a core manufacturer to calculate the number of turns required for a value of inductance. I use the factor when desigining toroidal inductors.
