The magnetic field
B around an infinitely long, straight conductor carrying a steady current can be described using the equation:
B=where:
B is the magnetic field,
µ0 is the permeability of free space,
i is the current through the conductor, and
r is the perpendicular distance from the conductor.
From this equation, we can see that
B is inversely proportional to
r, which implies:
B∝This relationship is characteristic of a rectangular hyperbola, meaning the graph of magnetic field
B versus distance
r will form a hyperbolic shape.
