Earth's magnetic field wikipedia
WebMagnetoreception is a sense which allows an organism to detect the Earth's magnetic field. Animals with this sense include some arthropods, molluscs, and vertebrates (fish, amphibians, reptiles, birds, and mammals, though not humans). The sense is mainly used for orientation and navigation, but it may help some animals to form regional maps.

There are different mathematical ways of representing the electromagnetic field. The first one views the electric and magnetic fields as three-dimensional vector fields. These vector fields each have a value defined at every point of space and time and are thus often regarded as functions of the space and time coordinates. As such, they are often written as E(x, y, z, t) (electric field) and B(x, y, z, t) (magnetic field). daniel bowman horse trainerWeb3.6Superparamagnetism 3.7Other types of magnetism 4Electromagnet 5Magnetism, electricity, and special relativity 6Magnetic fields in a material 7Magnetic force 8Magnetic dipoles Toggle Magnetic dipoles subsection 8.1Magnetic monopoles 9Units Toggle Units subsection 9.1SI 9.2Other 10Living things 11Quantum-mechanical origin of magnetism birthcare center korean dramaWebBy trapping the solar wind, the magnetic field deflects those energetic particles and protects the atmosphere from destruction.
