    Calculation of the maximum detectable distance of a magnet by a magnetometer

    siavosh1 posted a topic in Engineering
    Hi Dear, I have a single-component (Z-Axis) magnetometer with 60nT resolution. I want to calculate the maximum distance that this magnetometer can detect an N52 magnet with a volume of 1 cm³. So I used the following formula and inserted the values, and finally calculated the Z: Br = 1.47 T (for Magnet N52) B= 60 nT (magnetometer resolution) L=W=D=10mm Z=? My answer => Z= 1.579 m Keep in mind that I intended to solve this problem in the simplest possible way; the angle of view of the magnetometer is perpendicular to the magnet plate. My question is whether I have chosen the right formula? or do you suggest another solution for it.
