Answer the following question regarding earth’s magnetism:
If you made a map of magnetic field lines at Melbourne in
Australia, would the lines seem to go into the ground or come out of the ground?
The magnetic field lines would come out of the ground at Melbourne in Australia. The magnetic field lines emanate from magnetic north pole (near Geographic south) and merge at magnetic South Pole (near geographic north). Australia is near the magnetic north pole so, magnetic field lines will seem to be emerging.
