8.24.2.2 Test Method—If the magnet is imbedded/attached
as part of a magnetic component, extract the magnet from the
component. If the pole surface of the magnet is flat, calculate
the area using the appropriate geometric formula. If the pole is
not flat (for example, hemispherical), the pole surface area is
the maximum cross section of the magnet perpendicular to an
axis through the magnet poles (see Fig. 37).
NOTE 10—On multi-pole magnets use the area of the largest single
pole, which can be determined using magnetic field viewing film or
好好看看上面的这个note是怎么说的!
无论你的形状或磁极的方向是怎样的,都按标准做找到最大的磁极面积来计算就可以了。不是你想怎样做就怎样做的。
