Q: what is the use of placing the magnet in magnetic meridian while tracing the lines of force and locating the poles ? what will happen if we dont do so ? Q: why poles are not at extreme ends of a bar magnet and a bit inside ? Q: why do new poles develop when we break a magnet ?

3) The arrows u see are the molecular magnets(molecules in the magnet have magnetic properties and they make the magnet "magnetic" in nature), the red colour indicates the north pole, the green indicates south.
When u cut the magnet, only the length of the magnet changes, i.e it doesn't affect the direction of the alignment of the poles, hence once again the direction in which the arrow points becomes north pole.
