Morphology
The meaning 'a magnet that retains its magnetic properties...' is directly derivable from combining 'static' (unchanging, fixed) with 'magnet' (an object that attracts ferromagnetic materials). Although the precise technical nuance about retaining magnetization after an external field is removed is specialized, the core sense of a stable/unchanging magnet is predictable from the constituents and thus accessible to a B1 learner who knows both words.
Etymology
Static magnet comes from static (still, not changing) and magnet (an object that pulls metal). Imagine a magnet that always holds notes on a fridge without any power — it 'keeps its strength' even when outside magnetism or electricity is gone, so 'static magnet' means a magnet that stays magnetic on its own.
