🎬how the magnetic field vector points in the azimuthal direction and how its magnitude changes with d

The strength of the magnetic field is inversely proportional to the distance from the current-carrying wire. This fundamental principle of electromagnetism is visualized by the length of the arrows in the animation. The arrows representing the magnetic field vectors are longest close to the central wire and become progressively shorter as they get farther away, directly illustrating that the field weakens with increasing distance.
