Homework Statement



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.

Homework Equations



flux=BAcostheta

The Attempt at a Solution


i found the area of the cylinder first and i don't have any idea where to go from there. I am not really finding any helpful equations...

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