I’m not a physics student (I study maths biology and chemistry a level) but I was curious about something I found when playing with some magnets. I know the basics regarding magnets such as like poles repel and opposites attract. When I have two magnets and have them repel I feel a strong force in between them pushing one another away and when I put a small object in between, that strong force of repulsion from either magnet does nothing to the small light object placed in between even though such strong forces of repulsion are being emitted from the magnets (emitted is probably not the best word but hopefully you get the point). Could someone please explain how and why this works.

The magnets exert the strong force of repulsion on each other as each magnet has what is known as a magnetic field around it (just think of it as a region that lets other magnets know that a magnet is there).

Non magnet objects cannot experience the magnetic field hence no force exerted on it by any magnets.

The magnets are repelled due to this magnetic field, but not the small object (as that is not a magnet). Hence the magnets ‘feel’ the force but not the small object.

I hope this explains it ok, sorry if it’s not great. I know this isn’t the full physics behind it, but this is the basic principle behind your observations I think.

If there’s any inaccuracies anyone feel free to correct me.
