Circulation of a Mag field around a wire, what is the angle?

  1. Jan 12, 2016 #1
    Circulation of a magnetic field = closed loop integral ∫c B ⋅dl = μ0I

    B is mag field strength, dl is small line element, I is current

    Im imagining both B and dl point in the same direction from the diagram. So the dot product here, I picture as cosθ = cos0

    Is that correct way to think? This is not a homework question, I'm reading amperes law theory.
