Question

Why magnetic force are maximum in the poles? Why like pole of the magnet repel each other?

Answer 1

hii mate

Every magnet has a magnetic field around it which are represented by magnetic lines of force. The magnetic lines of force start from north pole and end at the south pole outside the magnet and and go from the south pole to the north pole inside the magnet. The density of the magnetic field lines is higher near the poles where the magnetic force is stronger. When two magnets are placed with their like poles facing each other, the lines of force are in opposite directions and hence like poles repel each other. When the unlike poles of a bar magnet face each other the magnetic lines of force are in the same direction and hence unlike poles attract each other. 

Answer 2

When two magnets are placed with their like poles facing each other, the lines of force are in opposite directions and hence like poles repel each other. When the unlike poles of a bar magnet face each other the magnetic lines of force are in the same direction and hence unlike poles attract each other... and secondly magnetic force are maximum becouse of presence of iron in them which make a pattern
Magnets attract iron due to the influence of their magnetic field upon the iron. ... When exposed to the magnetic field, the atoms begin to align their electrons with the flow of the magnetic field, which makes the iron magnetized as well..



hope it helps u
