Abstract: Even under open-circuit, Halbach permanent magnet (PM) machines may partially suffer from an irreversible demagnetization issue. In this paper, the relationship between PM segment number per ...

Abstract: Current investigators are devoting considerable effort to the analysis of self- and adjacent bit demagnetization. However, it is shown in this paper that recording demagnetization degrades ...

May 23, 2025 — A new experiment encodes quantum information in the motion of the atoms and creates a state known as hyper-entanglement, in which two or more traits are linked among a pair of ...

One wind turbine, for example, uses more than two tons of rare earth elements. Recycling rare earth elements from end-of-life products typically involves four stages: disassembly, demagnetization, ...
