Calculate the magnetic field intensity in the gaps of Example 9.18 for finite permeability of iron. Assume the relative permeability of iron is μr.
Example 9.18
A cylindrical magnet of length a, radius b, and uniform magnetization M is inserted in a magnetic path as shown in Figure 9.41.
The cross section of the magnetic path is constant and equal to that of the magnet. Two small gaps, each of length d, are also present. Other dimensions and properties are given in the figure. Assume permeabilities of the path are infinite, except in gaps and magnet, where the permeability is μ0. Calculate the magnetic field intensity H in each of the gaps.
