Question

When an iron bar is placed nearer to the north pole of a magnet, the south poles of the molecular magnets in the iron bar point towards ______.

Answer 1

1. When this iron bar is magnetized, molecules lose their random orientations and arrange themselves such that all the north poles point in one direction and the south poles point in the opposite direction.
2. All the molecules of the iron bar align themselves in the direction of the external magnetic field.
3. When an iron bar is placed nearer to the north pole of a magnet the south poles of the molecular magnets in the iron bar point towards the North pole

Hence, when an iron bar is placed nearer to the north pole of a magnet the south poles of the molecular magnets in the iron bar point towards the North pole.
