Coiled wire.

Explanation: For the same current, the magnetic fields from each loop of a coil add together, producing a much stronger and more concentrated field (inside a long solenoid B ≈ μ0 n I, where n = turns per length). A single straight long wire produces B = μ0 I / (2πr) at distance r, which is weaker near the center compared to a coil with many turns.
