Magnetic Field due to a Current Through a Long Straight Wire

Magnetic Field due to a Current Through a Long Straight Wire (cont.)
For a straight wire of final length:

Ampere’s Circulation Law
Circulation of the magnetic field intensity round the closed loop is equal to the current enclosed by this loop.
