Can you derive the formula for calculating inductance in a copper coil?
Why is the square of the number of turns used?
Thanks

The formulae that I have seen for an air cored coil are all approximations so I guess the answer is no, you can't derive a formula.Can you derive the formula for calculating inductance in a copper coil?

Agreed. I think I remember reading that Wheeler collected a lot of data and looked at many, many alternative expressions before settling on the formula now bearing his name.The formulae that I have seen for an air cored coil are all approximations so I guess the answer is no, you can't derive a formula.
