Unformatted text preview: A sufficient number of integration points (50)
are chosen along the Z-axis to adequately represent the coil. Only one point is specified through the coil thickness.
The Reduced Scalar Potential (RSP) is selected since only a source field is to be calculated. Results Comparison

A permanent magnet circuit consists of a highly permeable core, a permanent magnet (the darker shading in
the sketch), and an air gap. Assuming an ideal circuit with no flux leakage, determine the magnetic flux density
and field intensity in the permanent magnet and the air gap. Figure 169.1...
