Meminductor: Researchers discover new circuit element

https://techxplore.com/news/2023-04-circuit-element.html

"current and voltage properties are dependent on previous values of current or voltage in time, like a memory.... The motion of the winding for the negative half-cycle of current results in gradually smaller winding volumes being occupied by the ferromagnetic core thus resulting in lower values of inductance... 2D passive electromagnet interacting with pair of permanent magnets used as tool proving pinched hysteresis curve's existence within inductor leading to its mem- state, or memory-like nature"
