to North pole.
Reason The direction of magnetic field produced by a straight current carrying wire
depends upon the direction of current flowing through it.​

Answer 1

Answer:

Inside the magnet, the direction of field lines is from its south pole to its north pole. Thus the magnetic field lines are closed curves. The relative strength of the magnetic field is shown by the degree of closeness of the field lines. ... No two field-lines are found to cross each other.
