The origins of magnetic steel can be traced back to the 18 th century when scientists began experimenting with iron alloys. In 1820, Hans Christian Oersted's accidental discovery of electromagnetism ...

Variable reluctance (VR) sensors transform mechanical motion into electrical signals by exploiting changes in magnetic flux. As a ferromagnetic target moves past the sensor’s pole piece, the ...

Figure 1 Schematic diagrams of two superconducting flux qubit circuits. The conventional qubit (a) requires an external magnetic field to operate optimally, while the new flux qubit (b), using a ...

There are many types of magnetic field sensors on the market. A brief list would include (but not be limited to) these, with the more exotic devices first: The MEMS solutions are gaining market share ...
