The model is shown in the figure below. The center pole and yoke are made of steel. The coil is excited by a dc current. The Ampere-turns is 3000 which is sufficient to saturate the steel.

The problem is known under the name of TEAM 20. It is one of the benchmarks used in the industry for code validation. In this problem we will calculate the magnetic field.

Due to symmetry, only half of the model is created. The model consists of 4 components: the yoke (in blue), the center pole (in red), the coil (in yellow), and the air (in light transparent gray).

The figure below shows a half of the problem including the surrounding air layers.
