An effective transformer design requires a determination of the peak values of the magnetic flux, the magnetic field strength, and the permeability of a core at low and high frequencies. These ...

A Superconducting Quantum Interference Device (SQUID) is an extremely sensitive magnetometer that measures very subtle magnetic fields. It exploits the quantum mechanical properties of ...

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 ...

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 ...
