## Main Question or Discussion Point

Hello, I need help with calculating inductance of a toroid core. I tried googling and came up with 3 results, but they don't really help. Links are:

http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/indtor.html

http://www.nessengr.com/techdata/toroid/toroid.html

http://www.phys.uri.edu/~gerhard/PHY204/tsl267.pdf

The information I have:

Toroid inner diameter: 8 mm

Toroid outside diameter: 15 mm

Toroid height: 6 mm

Wire radius: 0.63 mm

Number of turns: 60

I need a formula that takes into consideration inside and outside diameter (or radius), height, wire radius, number of turns and permeability of the core. None of the formulas in above links seem to do that.

Thanks in advance.
