Magnetic flux in a straight wire to a cylinder

  1. Oct 25, 2008 #1
    1. The problem statement, all variables and given/known data

    A long, straight wire carrying a current of 3.00 A is placed along the axis of a cylinder of radius 0.500 m and a length of 5.00 m. Determine the total magnetic flux through the cylinder.

    2. Relevant equations


    3. The attempt at a solution
    i found the area of the cylinder first and i dont have any idea where to go from there. Im not really finding any helpful equations.....

    Obviously, you have to calculate the magnetic field due to the current.

    would i use B= (Moconstant)I/2pir??
