Permanent magnets are fascinating. They generate magnetic field and act asthe key component in compasses, motors, speakers for practical applications.They are also made into magnetic toys for entertainment and education withmagical magnetic tricks. Some of these tricks fueled the recent upsurge formagnetic-responsive objects including but not limited to a LK-99 mixture. Alack of full consideration of the magnetic interactions seems to be the reasonwhy some tricks like "half levitation" is misinterpreted, and the situation isnot really rectified in the following replications and discussions. Here Iwould like to go through some less commonly taught facts about real-worldpermanent magnets starting from the nonuniformity to their combined effectswith other factors. Based on these facts, I will also break down the situationof some examples of how permanent magnets diversely interact even with ordinaryobjects, as one may have seen from recent sources. I believe this discussion isuseful both in an informative and educational way, helping those who want tothink deeper about magnetic mechanism beyond a simple attract/repelterminology.
