    hey ; with magnets we use North and South

    but for example : what does north stands for ; indicate ?

    i mean, if u have for example a magnetised material
    lets say u got it magnetised by rubbing it with an other
    if the material has more positive charges than negative : do we say its a Norh or South ?

    To put my question more general :
    does North attract positive charges or negative charges ?

    North and south in magnets is just and old convention, coming from the time when people thought that there where magnetic charges (monopoles). You call north the side of a magnet which is attracted by the magnetic pole of the earth north. And south the other one.

    This has nothing to do with electric charges. Immobile electric charges are not attracted magnetic fields. But moving electric charges are deviated by magnetic fields.
