Magnetic Pole Reversal: Explaining the Paradox

AI Thread Summary
When a magnet is cut in half, each piece retains its north and south poles, resulting in two new magnets, each with a north and south pole. The misconception that the cut edges become like poles is incorrect; they actually form opposite poles. The magnetic field lines continue to flow from the north to the south pole, maintaining the polarity of the original magnet. This phenomenon aligns with the fundamental principles of magnetism, where monopoles do not exist in typical scenarios. Understanding this helps clarify the nature of magnetic fields and their behavior during division.

If the magnetic field lines are going from north to south pole then why when we cut a magnet from middle the two cutting edges become like poles. Common sense says that one edge should be north pole and other should be south . Can anyone explain ?

The cut edges can't be like poles. That would mean that one of the new magnets would have to either be a monopole or instantly flip its polarity.

All we can say is that "common sense" is right in this case. If you cut a bar magnet into two pieces, the two cut edges do NOT become like poles. The S and N poles of the original magnet become S and N poles of the new magnets, the cut ends become N and S poles. What made you think they became like poles?

I cannot explain this any more than I can explain why the sun sets in the north, water is dry, or sound moves faster than light. It is literally the opposite of what happens.

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
