> Magnets are only used in spinning storage right? In the 1970s, magnetic bubble memories were seen as potential replacements for disk drives (and, initially, even semiconductor RAM), but rapid improvements in what we now regard as traditional technology outpaced what could be done with bubble memory. I am pretty sure that bubble memory is unrelated to the phenomenon discussed here, beyond that it made use of a magnetic effect in a solid substrate. https://en.wikipedia.org/wiki/Bubble_memory https://en.wikipedia.org/wiki/Bubble_memory
