Because magnetic field is directly proportional to current and inversely proportional to the distance

"When magnetic field lines are drawn around a current carrying circular loop, it has been observed that they are close to its Axis. but these lines keep on diverging as we move away from the centre.
It is because when the distance increases the strength of the magnetic field falls. It is indicated through the decrease in the degree of the closeness of the lines of field.
