The correct answer is D) magnetic needle. A magnetic needle or magnetized rod is used in a magnetic compass.
This rod is positioned on a surface with low friction. It is allowed to rotate freely and align with the magnetic field on its own. The north end of the needle usually features some form of marking to distinguish it from the south end.
