If you have a real compass to hand, you can check whether your needle works by observing whether it points in the same direction as the needle in the compass. Remember that the magnet can affect the ...

It is these rotational forces in the liquid iron layer that lead to weak magnetic forces around the axis of spin. The magnetized needle in a compass can detect very slight magnetic fields.

Iron is magnetic so the liquid iron causes Earth to have a magnetic field. The needle of a compass is a small magnet that can turn. It turns around until its own magnetic field lines up with the ...
