Magneettiyksikkö

A magneettiyksikkö, which translates to "magnetic unit" in English, refers to a unit used in the measurement of magnetic quantities. Historically, various systems of units have been employed for magnetism, leading to different definitions of magnetic units. The most prominent of these systems is the CGS (centimeter-gram-second) system, which includes units for magnetic field strength, magnetic flux density, and magnetic potential.

In the CGS system, the unit for magnetic field strength (H) is the Oersted (Oe), and the unit for magnetic flux density (B) is the Gauss (G). Magnetic flux (Φ) is measured in Maxwells (Mx). These units are often used in older literature and some specialized fields.

However, the International System of Units (SI) is the modern standard for scientific and technical measurements. In the SI system, the unit for magnetic field strength is the Ampere per meter (A/m), and the unit for magnetic flux density is the Tesla (T). The SI unit for magnetic flux is the Weber (Wb). While magneettiyksikkö can broadly refer to any unit of magnetism, in contemporary scientific contexts, SI units are overwhelmingly preferred. Understanding the distinction between CGS and SI magnetic units is crucial for interpreting scientific data and avoiding confusion. Conversion factors exist between these systems, allowing for the translation of measurements from one to another.
