Abstract: An electromagnetic shielding body is formed of a first ferromagnetic member, at least one second ferromagnetic member disposed substantially in parallel to the first ferromagnetic member with a space and having a magnetic permeability different from that of the first ferromagnetic member, and an electrically conductive member disposed between and substantially in parallel to the first and second ferromagnetic members with spaces therebetween. A electromagnetic shielding panel is formed essentially by means of an electric connecting member electrically integrated with the conductive member, the electric connecting member being formed along an edge portion of the conductive member. Such panel is utilized for forming an electromagnetic shielding structure such as door, exit/entrance structure for a room, an electromagnetic shielding structure having a through-hole member, and an electromagnetic shielding room structure.

Abstract: There is provided an apparatus for measuring magnetic sources that exist in an object and produce magnetic fields outside the object. The apparatus comprises an element for detecting the magnetic fields which has a sensing portion placed in proximity with the object and adapted to incorporate an observing plane. The observing plane consists of a plurality of sensing blocks each containing at least three sensing planes on which a magnetic sensor is each mounted. The normal directions of the sensing planes are different from each other. The apparatus further comprises an element for evaluating three-dimensionally the intensities of other magnetic fields at given evaluation positions on the basis of values of the magnetic fields at the detecting element, and an element for obtaining data of the magnetic sources on the basis of the intensities of the other magnetic fields evaluated by the evaluation element.
