Biot Unit | All you need to know

A biot (Bi) is a unit of electric current equal to 10 amperes in SI units, making it identical to the abampere. The unit is named after physicist Jean-Baptiste Biot and was used historically in the CGS electromagnetic system. The biot appears occasionally in historical physics literature, particularly in works discussing magnetism and electromagnetism from the late 19th and early 20th centuries. Modern scientific practice uses SI units (amperes) exclusively, making the biot notation rare in contemporary applications. Researchers reviewing historical scientific works or studying classical electromagnetism in traditional textbooks may encounter biot notation.
