Hakudō: Levitation

By creating a very strong localized magnetic field, Kenshin can levitate himself or other objects. This technique is based on the diamagnetic properties of matter. Diamagnetic materials repel a magnetic field, but normally the diamagnetic nature is overpowered by the material's ferro or paramagnetic nature. That is why Kenshin needs to create a very strong magnetic field in order to use this technique.
