Attoteslas

Attoteslas is a unit of magnetic flux density. It is derived from the SI prefix "atto," representing 10 to the power of negative 18, and "tesla," the base unit of magnetic flux density. Therefore, one attotesla is equal to 10^-18 tesla. The tesla (T) itself is defined as one Newton per ampere-meter (N/(A·m)), or one weber per square meter (Wb/m^2). Magnetic flux density, often denoted by the symbol B, is a vector quantity that describes the strength and direction of a magnetic field. It is a fundamental concept in electromagnetism and plays a crucial role in various scientific and technological applications. The attotesla unit is exceptionally small, indicating an extremely weak magnetic field. Such minuscule values are typically encountered in highly specialized areas of research, such as quantum physics experiments or the study of extremely subtle magnetic phenomena at the atomic or subatomic level. Due to its infinitesimal magnitude, the attotesla is not a commonly used unit in everyday applications or general scientific discourse. It serves primarily as a precise measure for theoretical calculations or experimental results in fields dealing with the weakest detectable magnetic influences.
