Diamagnetism can make levitation possible. How? Diamagnetic materials are repelled by magnetic fields. The most diamagnetic materials are graphite and bismuth. Technically, everything is diamagnetic but the force of it is very weak. Diamagnetism is present in everything, but is only observable if other types of magnetism, such as paramagnetism, ferromagnetism, ferrimagnetism, antiferromagnetism, etc. do not overwhelm it. Most of the time, diamagnetic materials’ effect is very weak. Levitating humans are possible with this, since we are mostly water and water is diamagnetic, but the magnetic forces required would be enormous due to the relatively weak force of repulsion. Overall, diamagnetism sounds pretty awesome, right? Well, it’s a lot more complicated than it seems.

There’s a lot more behind diamagnetism than what it seems like. Diamagnetic materials’ electrons change direction, creating small currents which oppose the external magnetic field, when an external magnetic field is applied to the material. Basically, the electrons orientate themselves so that they do not match up on either side. Usually, on a regular magnet, a North Pole attracts to a South Pole and vice versa, because opposites attract, but in diamagnetism, the electrons orientate themselves so that a North Pole matches up with another North Pole and vice versa. Because of this, they will repel each other. The drawing below explains it visually. They repel each other, making levitation possible with…
