摘要： A small-sized magnetic marker is provided which can be used with good sensitivity in both a so-called large Barkhausen type system and a so-called high permeability type system. The magnetic marker includes a soft magnetic material with its length not longer than 70 mm. When an external alternating field having magnetic field strength of not higher than 0.2 Oe is applied, the soft magnetic material generates abrupt magnetization reversal with a magnetic flux change of not less than 8.0 × 10 -9 Wb. It is preferable that a fluctuation in the magnetic field strength, where soft magnetic material generates the abrupt magnetization reversal, is not higher than 0.1 Oe.

摘要： The present invention relates to a magnetic manipulation and navigation system for moving a magnetic element through a body comprising at least six electromagnets (24) with soft-magnetic cores arranged in a predetermined position to said body. It allows for the operation of one or more of the electromagnets in the non-linear regime of the magnetization curve of the cores. The system comprises at least one magnetic field sensor (104) at one or more predetermined positions outside of the operating region. While during operation in the linear region no feedback is required to set the magnetic field strength, during operation in the non-linear region feedback from the magnetic field sensors is used for closed-loop control. The system allows for operation in two separate modes, an open-loop mode operation in the linear regime for fast control signals such as they are required for stabilization during displacement of the magnetic element and a closed-loop operation in the non-linear regime for higher field strengths such as they may be required to apply forces and moments on the magnetic element while it is in contact with a surface.

摘要： A small magnetic marker that can be used with high sensitivity both in a generally-called large Barkhausen system and a generally-called high permeability system. The length of the magnetic marker including a soft magnetic material is not more than 70 mm. The soft magnetic material, when an alternating magnetic field of a strength less than 0.20e is applied thereto, causes steep magnetic reversal with a magnetic flux change of more than 8.0 x 10-9 Wb. The variation of magnetic field strength when the soft magnetic material causes a steep magnetization reversal is preferably 0.10e or less.
