Magnetic field annihilators: invisible magnetization at the magnetic equator [PDF]
Geophysical Journal International, 2003 SUMMARY Some distributions of magnetization give rise to magnetic fields that vanish everywhere above the surface, rendering these distributions of magnetization completely invisible. They are the annihilators of the magnetic inverse problem. Known examples are the infinite sheet with constant magnetization and the spherical shell of constant ...
