Magnet Physics
Magnets are a common household product in many places. You can find them on refrigerators, mirrors, and on the occasional car. But delve deeper than that and they are everywhere. Refrigerator doors, treadmills, vacuum cleaners, computers, and even phones use magnets to function properly. Although magnets are so common, most people don’t know the science of how it works. They are made of metal, and while the type can vary, they all have an invisible magnetic field that surrounds them.
One fact about magnets is that they only work on motion. A single particle with an electric charge that is simply existing, will generate an electric field. This field surrounds the particle on all sides and affects the movement of particles around it. If a similarly charged particle is nearby, it will be pushed away. If an oppositely charged particle is far away, it will be drawn towards it. But if you move that electric particle, a new field is generated. This new field is very different because it twists around the particle, always perpendicular to the direction of movement. What’s more, another particle nearby will only feel the effects if it's also in motion and the force inflicted on the particle will be perpendicular to the direction of its motion. This field is most commonly called the magnetic field.
Another fact about magnets is that monopoles might exist. Because all magnetic fields that exist are generated by moving charges, north and south magnetic poles can never be separated from each other, always coming in pairs. If you were to cut a magnet in half, you would still have two opposite poles on two different magnets, just with a weaker force. To clarify, a monopole can be loosely classified as a magnet with one single pole on it, for example a magnet with just a north magnetic pole would be a monopole. This is simply a theory though, and has never been seen before. But recent studies have shown that, theoretically, if a single monopole existed in the whole entire universe, that would cause the quantitation of charge, since the magnetic effect isn’t affected by distance.
While magnets are very advanced right now, in the future they could possibly become much more stronger. Different metals could be fused that are more lightweight yet more powerful at the same time. Currently, magnets are currently made of neodymium, which when combined with iron and boron, fuses into a very powerful magnet that is yet also relatively cheap. The metal used will likely change into something that is much more powerful and we might be able to convert them to liquid and gas forms, and possibly incorporate them into nearly all household objects such as windows, tables, and even chairs.
