FTP, this law was named after two French physicists that determines the magnetic field at a point near a current.
This law follows the inverse square law pattern seen throughout physics. Ampere's law is often used as a substitute for this equation, since the line integral around an enclosed current, usually a circle in simple problems, is easier to calculate. In this law however, the cross product of the current vector and distance vector must be calculated.
