WebApr 11, 2024 · It is the most magnetic of all the naturally occurring minerals on Earth, and is known as a ferromagnetic. This means it is attracted to a magnet but can also be magnetised to become a permanent magnet itself. Magnetite can be found naturally magnetised, these pieces go by the name Lodestone and will attract metals. WebReceptor cells containing crystals of magnetite could register changes in magnetic fields and report this information to the brain. This is almost identical to what magnetotactic bacteria do. They have structures containing nanoscale magnetite crystals called magnetosomes. These essentially act as biological compasses, allowing the bacteria to ...
