The north pole of a magnet is the pole that, when the magnet is freely suspended, points towards the Earth's North Magnetic Pole which is located in northern Canada. Since opposite poles (north and south) attract, the Earth's "North Magnetic Pole" is thus actually the south pole of the Earth's magnetic field.
As a practical matter, in order to tell which pole of a magnet is north and which is south, it is not necessary to use the Earth's magnetic field at all. For example, one method would be to compare it to an electromagnet, whose poles can be identified by the right-hand rule. The magnetic field lines of a magnet are considered by convention to emerge from the magnet's north pole and reenter at the south pole.

1, Michining &Tolerance of 40H sintered NdFeB magnet Arc shape
Generally, NdFeB magnets must be machined using diamond-grinding techniques. Sometimes, machining operations may be performed on NdFeB materials using carbide tools, but surface finishes thus obtained may be less than optimal.
The Standard tolerances for NdFeB magnets are +/- 0.1mm for ground dimensions, but sticter tolerances are possible if specially required.
