    摘要： Embodiments described herein provide magnetic permeability measurements of ferromagnetic wires. In one embodiment, an apparatus comprises a non-magnetic wire retainer having a circular groove that holds a ferromagnetic wire for measurement. The apparatus further comprises a magnetic field generator proximate to the non-magnetic wire retainer that provides a substantially uniform magnetic field along a circumference of the circular groove. The apparatus further comprises a force sensor mechanically coupled to the magnetic field generator that measures an attractive force between the magnetic field generator and the ferromagnetic wire for determining the magnetic permeability of the ferromagnetic wire.

    摘要： A laminated structure may be tested for weak joints by passing a magnet over the surface. If the outer surface is of a magnetic material, weak bonding forces will be overcome by the magnet which causes deflection of the magnetic layer, relative to a non-magnetic substrate. The deflection is sensed and signifies the detection of a weak bond area. The testing procedure is accomplished without destructively testing a structure.

    摘要： A cantilever beam is employed to place a magnet in proximity to a sample while the sample is maintained at a superconducting temperature. The magnet causes the sample, assuming it is superconductive, to itself generate a magnetic field which interacts with the magnet. Means are provided for measuring the movement of the cantilever beam, such movement being a measure of the interaction of the sample's magnetic field with the magnet. Several types of cantilever beams are disclosed, one of which is adapted to move in a direction orthogonal to the surface of the sample and another of which is adapted to move parallel to the surface of the sample. This enables the obtaining of quantitative measurements of the bulk properties of high temperature superconducting materials.
