(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

You have 12m of 0.50mm diameter copper wire and a power supply capable of passing 17A through the wire.

What magnetic field strength would you obtain inside a 2.0cm diameter solenoid with the wire spaced as closely as possible?

2. Relevant equations

B=u_{0}nI

3. The attempt at a solution

I found the number of loops by

D=.002+2*1*10^{-3}m (diametre plus 2 radi of wire)???

then n=12/circumfrence =173.6turns (C=pi*D

then I subbed all the values and got 0.0037T which is wrong

all help appreciated - I think my problem is in calculating the number of turns??
