why does two like poles of a magnet repel?

Answer 1

Because that is the rule of magnetism. Unlike poles attract and like poles repel.

From what I remember of my 'O' Level Physics class, the like poles repel because electrons (the negatively charged particles) and protons (the positively charged) cannot attract each other, whereas electrons can attract protons and vv.

Answer 2

Magnetic force is nothing more than a force caused by a current. Magnetic materials are magnetic because there is current within them. The underlying force is the coulomb force, which tells us that like charges repel.

Magnetism is fundamentally related to electric force.

Answer 3

one pole of the magnet sends out the magnetism ... the other takes it in ... like a flow of electricity.

Like poles either both are pushing out or looking to take in ...

Answer 4

magnets show such close characteristics that it looks liike 'lines of force' emanate from them(magnetic field)...north poles 'ooze' the lines outwards and the south poles,'inwards'...the lines behave like elastic rubber......


two sets of lines that emanate from like poles therefore have the same direction....when they r brought together,head on,they behave like they r compressed by each other,just like rubber bands....obviously they try to 'push' each other out and hence the repustion of like poles


.when unlike poles r brought together,the lines that flow in opposite directions behave like they r being streached by one another....this makes them do the 'equal and opposite reaction' of getting pulled closer together...hence the attraction of unlike poles

Answer 5

Because positive is attracted to negative. Positive and positive repel themselves, as do negative.
