Task: Question Generation
Input (English): Background Paragraph: The device in the circuit in Figure above is an ammeter. It measures the current that flows through the wire. The faster the magnet or coil moves, the greater the amount of current that is produced. If more turns were added to the coil, this would increase the strength of the magnetic field as well. If the magnet were moved back and forth repeatedly, the current would keep changing direction. In other words, alternating current would be produced. This is illustrated in Figure below . 
Story: James is testing the strength of electromagnetic fields. He takes two lengths of copper wire and coils them. His first coil, A, has a weaker magnetic field than his second coil, B.
Output (English): Will increasing the number of turns in a coil increase or decrease the strength of the electromagnetic field?
