Magnetic fields are invisible forces that exert influence on magnetic materials and charged particles. They are produced by moving electric charges, such as the flow of electrons in a wire, or by intrinsic magnetic properties of materials like iron. The Earth itself has a magnetic field, generated by the movement of molten iron in its outer core, which protects the planet from solar and cosmic radiation and is responsible for phenomena such as the auroras. Magnetic fields are quantified by their strength and direction, and they are depicted visually through field lines that emerge from north magnetic poles and enter south magnetic poles. These fields play crucial roles in various technologies, from simple compasses for navigation to complex applications like magnetic resonance imaging (MRI) in medical diagnostics. Additionally, magnetic fields are fundamental in physics, influencing many processes from the atomic to the cosmic scale, including the behavior of plasmas in stars and the interstellar medium.
