    摘要: An electromagnetic relay having a coil core which carries a coil. The coil is connected to one end to the short limb of an L-shaped magnet yoke, on a long limb of the L-shaped magnet, a hinged armature is supported in a manner which allows the armature to pivot about a pivot axis on the long limb of the magnet. In order to achieve a precisely defined switching behavior which is concurrent for the relays of a series, the length of the coil core is produced by means of upsetting as a function of the height of the pivot axis above a base area of the magnet yoke on which the coil core is secured, with the result that the position of the hinged armature with respect to a pole face of the coil core is precisely defined.

    摘要: An apparatus for measuring weak, location-dependent and time-dependent magnetic fields emitted from a source situated in an examination subject includes a sensor arrangement having at least ten gradiometers of the first order, each gradiometer being inductively coupled to a DC-SQUID. The sensor arrangement and the examination subject are disposed in a room which shields the examination subject and the sensor arrangement from magnetic fields. The room has a shielding factor of at least 10 for magnetic alternating fields having a frequency of 0.5 Hz, the shielding factor increasing with increasing frequency. A method for operating the apparatus is also disclosed.
