    摘要： PROBLEM TO BE SOLVED: To accurately detect a surge current penetrating for a short time of time. SOLUTION: A protection element (such as an arrester 12) protects an apparatus 25 to be protected from surge currents i penetrating into line terminals L1, L2 or a grounding terminal E. Surge current detection devices 30-1 to 30-3 are provided on respective conductors 11-2, 11-3, 11-5 connected to the arrester 12. Each of the surge current detection devices 30-1 to 30-3 includes a magnetic flux concentration member 40 by which a magnetic flux produced by the penetrating surge current i is concentrated in a given detection area in high density, and a magnetic material sheet 50 positioned on the given detection area. The magnetic material sheet 50 includes a recording layer capable of recording and erasing the penetration state about the surge current i. A plurality of microcapsules, in which magnetic particles varying their magnetic orientation by a concentrated magnetic flux are sealed in a state suspended in a liquid, are arranged in the recording layer having a structure visually recognizable from outside.

    摘要： PROBLEM TO BE SOLVED: To provide a magnetic probe for achieving a high spatial resolution in the order of several nm.
    SOLUTION: When a paramagnetic seed 31 is fixed to the inside of the tip of a tubular vessel 34 filled with paramagnetic colloid particle dispersion and the tip is brought closer to a magnetic field, a paramagnetic colloid particle 32 is coagulated in a chain with the paramagnetic seed 31 as a starting point, and the length of the coagulation depends on the strength of the magnetic field. When the coagulation of the paramagnetic colloid particle 32 formed at the tip of the tubular vessel is observed by utilizing the phenomenon, magnetism is detected and a new magnetic probe 30 utilizing a mechanism totally different from that of the conventional magnetic probe 30 is composed. The magnetic probe 30 detects magnetism even if ultra-fine particles of a grain size of approximately several nm are used as the paramagnetic seed 31 fixed to the inside of the tip of the tubular vessel 34, thus achieving a high space resolution in the order of several nm.
