More toroid information

Filed Under (Homebrew, Reference Material) by Jonathan on 22-03-2010

I was working on a project awhile back and really needed some Toroid information (just type toroid in the search box and a few results will pop up).  I just found a few more I will indeed keep for future reference.

There is some info on the UnitMath website on various information on mathematical formulas used to calculate inductance, including:

Coaxial cable
Round Parallel Wires
Round Wire over a Ground Plane
Straight Round Wire
Air Core Coil ( Multi-Layered )
Air Core Coil ( Single-Layered )
Toroid with a Square Cross Section

Check out more at:

Over at 66Pacific, I found an online calculator that can do some of the math for you.  In addition to that, they also have the following calculators:

Wire Gauge & Diameter
Magnetic Loop Antennas
Capacitance (Capacitor Design)
Capacitive Reactance (Xc)
Inductive Reactance (XL)

All of these can be found at:

If you know of any other good ones, comment below.
