Morphology
The meaning is directly compositional: a 'magnet' that has the shape of a 'bar' (a long, rigid piece), so the compound denotes a magnet in the form of a bar. This is a simple noun-noun descriptive pattern that is cross-linguistically common and should be clear to a B1 learner who knows both constituents.
Etymology
Bar magnet comes from its shape: a straight piece of metal that is a bar and is also a magnet. Because the metal has a strong 'north' end and a strong 'south' end, the name helps explain why it pulls iron and moves compass needles.
