I have a simple question here that I seem not to be able to figure out. If you have a regular bar magnet, it emits a magnetic field around it. So, if you create an experiment and found out how far that field reached, you would see that the field doesn't go very far. Maybe like 3 inches (~ 7cm). (This is for a regular, bought at the grocery store bar magnet). I would also bet that if you found a way to make a magnet that instead emitted an electric field, it would have the same result: not very far. So, if electromagnetic radiation is just these two fields put together, then why do they go much farther than electric and magnetic fields individually? Also, why do they carry energy, when individual electric and magnetic fields alone are just force? Thank you.
