The factor that affects the direction of the current induced in the wire is **the direction in which the wire moves**. According to Faraday's law of electromagnetic induction, the movement of the wire through the magnetic field determines the direction of the induced current, which can be determined using the right-hand rule. The other options provided—thickness of the wire, the direction of the needle on an ammeter, and the type of magnet—do not affect the direction of the induced current in the same way.
