For example, a 2022 study proposed a hybrid-magnet variable-flux permanent magnet synchronous machine featuring a variable series-parallel magnetic circuit.

He envisioned that collinear antiferromagnets can function as "electrical circuits" with the two magnetic sublattices connected in parallel.

Linearized equations are derived which govern the stability of a viscous, electrically conducting fluid in motion between two parallel planes in the presence of a co-planar magnetic field. With one ...
