... Therefore, magnetic field inside a toroid varies as 1/r and hence is non-uniform. If r is large compared with the cross sectional radius of the torus, however, the field is almost uniform inside the toroid. For an ideal toroid, in which the turns are closed spaced, the magnitude of the magnetic fiel ...

... Recall that the linear charge density is 1 C/m and the unit of length is 1m. Whenever there is a relationship between two physical quantities expressed in the form of an equation, the units on both sides must be the same. This requires that the coefficient α in the equation λ(x) = αx has unit C/m2. ...
