1. The problem statement
I'm doing a stimulation. Here is a picture of it.

The questions asks: when moving the voltage slider on the battery and dragging it all the way from right to left, what happens?
- compass flips or stays the same.
- magnetic field flips direction or stays the same.
- current flows in the opposite direction or in the same direction.
I know that current stays the same and that the compass flips.
Since the current stays the same, does that mean the magnetic field direction stays the same? When I move it, it seems like the magnetic field lines above and below the current in the wires flips, while the area inside the coil of wire stays the same.
