Question

what is the direction of megnatic field lines of a magnet​

Answer 1

Answer:

It's a convention that magnetic field lines are drawn from north to south. Because we have defined the magnetic field lines to show the direction of the magnetic force on a north pole. Hence, they are defined as north to south. P.S.: The field lines don't "repel" from north pole or "attract" to south pole.
