A magnet moves through a coil of wire as shown. Magnetic poles are produced at the two ends of the coil as the magnet enters and as the magnet leaves the coil. Which pole is induced at P when the magnet enters the coil and which pole is induced at Q when the magnet leaves the coil?

1. Apole at P when magnet enters the coil: N; pole at Q when magnet leaves the coil: N
2. Bpole at P when magnet enters the coil: N; pole at Q when magnet leaves the coil: S
3. Cpole at P when magnet enters the coil: S; pole at Q when magnet leaves the coil: N
4. Dpole at P when magnet enters the coil: S; pole at Q when magnet leaves the coil: S
