magnetic core singular

Morphology

magnetic + core

This is a straightforward adjective + noun composition: a B1 learner who knows 'magnetic' (having magnetism) and 'core' (central part) can infer it denotes a core that is magnetic. The computer-science sense (a ferrite ring used for memory) is a specific technical instantiation of a magnetic core, so the basic meaning is directly derivable from the constituents.

Etymology

Magnetic core comes from early computers that used tiny ring-shaped magnets to store information. The word core named each small ring and magnetic showed how a wire passed through the ring set or read 'one bit', so the rings became the machine's 'memory'.
