Homework Statement
You have a 1.2-m-long copper wire. You want to make an N-turn current loop that generates a 0.60 mT magnetic field at the center when the current is 1.5 A. You must use the entire wire.
Homework Equations
What will be the diameter of your coil?
The Attempt at a Solution
I tried applying this formula d = sqrt ( (mu*L*I/pi*B)) and keep getting a really small number =0.000021 m
What am I missing here??
