Magnetic flux density and magnetic intensity. Magnetic flux density (also called Magnetic density) is symbolized by B, and is a force per unit of sensitive element, which in this case is a current. B is a vector magnitude, and is calculated as the magnitude of the magnetic force per unit of current in a given elemental length of a conductor.
