Reference: AQA
Iron filings sprinkled on a card around a straight wire form concentric circles centred on the wire, while a solenoid produces a field pattern similar to that of a bar magnet.
For a straight wire, concentric circles centred on the wire; for a solenoid, lines outside like a bar magnet and parallel lines inside.
