Abstract
The use of magnetized spheroids has attracted considerable interest as a building block to model and predict the static magnetic fields around steel structures. Defence R&D Canada (DRDC) has made effective use of magnetized prolate spheroids for the near field magnetic modelling of naval ships as required for mine simulation studies. For some geometries however, oblate spheroids may provide a more realistic representation of the structure. In particular, presented here is the derivation of the scalar magnetic potential and magnetic fields arising from a transversely magnetized oblate spheroid. Additionally, the solution is verified to produce; the results for a sphere, a point dipole in the farfield and lastly a transversely magnetized prolate spheroid.
