[mag′ned·ik ′shel] (electromagnetism) Two layers of magnetic charge of opposite sign, separated by an infinitesimal distance.

Magnetic Shell

 

an infinitely thin double magnetic layer formed by magnetic dipoles. Under certain conditions the magnetic field of a magnetic shell is equivalent to the field of a direct current flowing along the contour of a shell. The equivalence between a magnetic shell and a closed linear current is used in electrotechnical calculations.
