Subject: calculating inductance
i used to have a bookmark for a web page that would allow you to enter
parameters to calculate the inductance of various shapes. does anyone have
this link? i am specifically looking for a formula for a toroid. i also
remember something about the permitivity (i think that was the word) of the
substance. what is the permitivity of ferrite?
