1 Engineering magnetics -- practical introduction to BH curve
Recommended as a practical grounding in magnetic cores and BH curves, aimed at inductor design but useful for anyone puzzled by ferrites and magnetism.

ferrite cores
4 videos. Ranked by independent recommendations, not by views.
2 Magnetic Logic - Forgotten Technology
Mostly shared without comment, with brief mentions pointing to it as an illustration of ferrite cores and logic built from magnetics.
3 Crystal oscillator - Drive Level measurement
A FesZ Electronics video credited with showing how wire wound on a ferrite core can serve as a workable homemade AC current probe.
4 Servo Jitter - Solution
Suggested as a fix to try for twitchy servos, showing ferrite rings used to calm the movement once current has been ruled out.
