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.
