Document Summary
North pole which is south seeking pole. South pole which is north seeking pole. If we make a magnet in half they will still have a north & south pole, . ( meaning only one pole such as magnetic dipole: we cannot completely isolate a single magnetic pole. a dipole consists of two opposite poles separated by some distance. Direction of the magnetic field is where the compass will point shows that magnetic field is a vector. Earth behaves like a large magnet. since unlike poles attract, the south pole of the earth"s magnet must point in a northerly direction. The north seeking pole of the compass aligns itself northward along the field lines produced by the earth. The axis of the earth"s magnetic field, though, is not aligned exactly with the earth"s axis of rotation. since the rotational axis defines geographic or true north, the compass needle does not point exactly at most location.
