Performance. Does stacking magnets make them stronger? Can I increase the strength of a magnet I already have? Where on a magnet is the magnetic pull strongest? If I use two magnets to attract to each other, is the total attracting force equal to that of both of the individual pull forces of each magnet combined? read more
If you hold the magnets in your hands and bring them together, at some point the force increases so suddenly, that your muscles don't have enough time to react, and the magnets "snap together". They also "snap together" if you put them e.g. on a table and slowly push towards each other - in this case, once the force between magnets becomes high enough to overcome friction, they start moving towards each other and the force increases, increasing their acceleration, until they collide. read more
Each magnet has a north pole and a south pole (named after the earth's magnetic north and south poles), and the north end of one magnet will stick to the south end of another magnet. But if two north poles or two south poles are placed near each other, the magnets will push each other away. read more
All magnets have two poles that emit opposing forces. The ends of a magnet are called the north-seeking pole and the south-seeking pole. They got these names because, when suspended on a string or immersed in water, the north-seeking pole will point toward the Earth's North Pole, while the south-seeking pole will point toward the Earth's South Pole. read more
