Problem C3: The figure above shows a cylindrical wire of radius R. The wire is infinitly long and has a total current I. The current I is uniformly distributed in the wire. What is the ratio of the magnetic field B₁ at the point r₁=R/n₁ to the magnetic field B₂ at the point r₂=n₂R? That is, if B₁/B₂ = n₃, what is n₃?

n1 =	n2 =	Input n3:
