抄録

Magnetic shielding by a spheroidal shell is studied. In order to see the shielding power of a flat shell in general, comparison between spheroidal, cylindrical and square shells is made in regard to shielding power. It is concluded that the flatter the shell becomes, the weaker is the shielding power. For the purpose of efficient shielding, we have to use a round shell that has no sharp edges and comers. It is doubtful that a flat case made of highly-permeable metal, that is on sale in the market, works as a shielding device for a floppy disk.
