In this study, we derived an approximate analytic function for the off-axis magnetic field of a finite-length solenoid by using the magnetic vector potential of a circular current loop. We verified that the derived analytic function reduced to a well-known magnetic field formula on the vertical axis of the solenoid and also inferred the magnetic field on the horizontal axis of the solenoid. Furthermore, we investigated the magnetic field at arbitrary points satisfying the approximate conditions through a simulation performed using Wolfram Mathematica.
