What happens if a bar magnet is cut into two pieces: (i) transverse to its length, (ii) along its length?

DEAR ADITYA 
when u will cut a bar magnet along its length , then the small piece also act like a magnet again , but the magnatic strength will decrease in the 2^nd case . 
along its length , – it only behave as a bar magnet again , and strength decreases , 
and if u will cut it transverse to its length , north and south pole remains same again . 

so, at all no change will happen with that 
HOPE IT CLEARS
