Magnetic field inside of a long rotating cylinder

2015-12-21  I need to find out what is the magnetic field inside a rotating long cylinder with a charged density σ. The cylinder rotates around its axis with angular speed ω. All of the parameters are constants. I've tried using Amper's law but I can't seem to get to the right answer. J = λ ⋅ v = σ ω R d r.
