Homework Statement
Prove that the number of turns per length on a solenoid is equal to 1/(diameter).
Homework Equations
A= 2(pi)(R)
The Attempt at a Solution
number of turns= length/(2pi*radius)
number of coils per length=(length/(2pi*radius))/length
number of coils per length=1/(2pi*radius)
I'm not sure why I have an extra pi. Did I do something wrong?
Thanks for any help.
