| contents | We measure the magnetic field produced by a linear octupole formed by four magnets placed in such a way that both their magnetic moments and their quadrupole moments cancel each other. The magnetic field is measured with the magnetic sensor of a smartphone together with a suitable app, using the Android operating system. The main objective is to determine the dependence of the x-component of the magnetic field with distance and compare with the theoretical result that tells us that this dependence is a quintic decrease. |
