Uh... Been there, done that?  It was called "core memory" [after
the doughnut-shaped magnetic ferrite cores used to store each bit],
and was very widely used in the 1970's for the main memories of
systems such as the IBM 360 and the DEC PDP-10, etc. *Much* higher
dynamic power and *much* lower density per bit than today's DRAMs
[though core memory did have the advantage of being nonvolatile when
the power was off].

Or maybe you're thinking of "disk drives"?  I hear that a number of
people are still using those...  ;-}  ;-}
