In the figure shown, consider a long hollow cylindrical metal pipe of inner radius a and outer adius b in which flows a current I uniformly distributed over the cross section of the conductor. P F I In order to calculate the magnetic field at a point Pa distance R from the axis, where a < r < b i.e., P is within the metal, we carry out a line integral along a path which encloses all the current in the conductor. we evaluate a line integral along a path that passes through the point P.

A toroid has a major radius R and a minor radius r and is tightly wound with N turns of wire on a hollow cardboard torus. as shown half of this toroid, allowing us to see its cross section. If R >> r, the magnetic field in the region enclosed by the wire is essentially the same as the magnetic field of a solenoid that has been bent into a large circle of radius R. Modeling the field as the uniform field of a long solenoid, show that the inductance of such a toroid is approximately L ≈ 1/2 μ0N2r2/R
