A magnet passes through a coil of wire at constant speed. The coil is connected to an oscilloscope. The diagram shows the trace formed on the screen. The experiment is then altered and a different trace is produced. Which statement explains why the new trace differs from the original trace?
- AThe coil is longer and the other pole of the magnet enters the coil first.
- BThe coil is longer and the same pole of the magnet enters the coil first.
- CThe coil is shorter and the other pole of the magnet enters the coil first.
- DThe coil is shorter and the same pole of the magnet enters the coil first.
