The length of a wire forming a solenoid

  1. Mar 28, 2005 #1
    I need help! I am unsure of what to do.

    A solenoid 1.33 m long and 0.0260 m in diameter carries a current of 17.8 A. The magnetic field inside the solenoid is 22.4 mT. Find the length of the wire forming the solenoid.

    The only information I have is the equation B=(Mu sub 0)*n*i
    Where Mu sub 0=4*pi*10^(-7) (T*m)/A

    If you can find the number of turns (n), and you know the circumference of each turn (given), then you know the length of the wire.
