Abstract
A magnetic field measurement system including a pick-up coil is not moved but fixed. Strips of superconducting material are arranged in a plane with narrow slits between the strips. The strips are moved very near the pick-up coil along the plane. From output variations of a SQUID magnetometer during the movement, a magnitude of a static field perpendicular to the plane of the strips is obtained.
