magnetic field cilinder

[jackxxny]

1. The problem statement, all variables and given/known data
I have a cylinder with 12 long parallel wires placed at the position of the hour on the clock.
each wire carries the corresponding hour in amperes. example the wire at 1 o'clock carries 1 A, the one at 2 carries 2 A and so on.
i need to find the magnetic field at the center of the cylinder.

2. Relevant equations
I don't really know where to start.


3. The attempt at a solution

[jackxxny]

my question really is how do i account for all of the wires?

Find the magnetic field from each wire, then add them up. Note that the magnetic field is a vector, so direction matters.
