how to use a compass
for north and south hemispheres
compass and magnetic feild
compasses are magnetically charged needles and lead to the nearest magnetic point (north or south pole). the compass is used to travel.
the magnetic field is created by the inner core turning against the outer core. this may scare you but it does no harm. actually the magnetic field is the reason you exist.
for the northern hemisphere the red compass needle points north because the nearest magnetic point is the north pole (in most cases). to use the compass, determine the direction you want to travel and use your compass to find that direction and start traveling.
this could be different because some compasses point only south or only north. but some point to the closes magnetic center. in other words, the red needle isn't always north.
