If she connects the battery in the opposite direction, the magnetic field would reverse its poles.

What is magnetic field?

The magnetic field is the region of space where an object experiences the magnetic force and obtain magnetic properties.

A wire is connected to the positive end of the battery and curls around an iron nail and connects back with the negative side of the battery. This arrangement will let the current flow from the positive end of the battery towards the negative terminal of the battery.

If the battery is connected in the opposite direction, the current will flow from negative to positive terminal.

Therefore, If she connects the battery in the opposite direction, the magnetic field would reverse its poles.
