  • Conventions Why Is The Direction Of Magnetic Field From

    since magnetic field lines are the path taken by a hypothetical north pole when it is in range of a magnetic field of a magnet it is clear that the direction of hypothetical north pole would be from north pole to south pole of a magnet not even outside the magnet but inside the magnet too because north pole of magnet will repel the hypothetical north pole inside and outside the magnet.
