I need to presence sense a row of several magnets (6-20, depending on the machine size) that are repeatedly placed onto and collected from a steel surface. I need to determine a signature of the magnetic field of the group, then check each time they are placed/collected to ensure that none are missing. Thought is to run a strip of the desired material close alongside the row, and check the resistance (signature) with an ohmmeter.I‘d also be interested in any other ideas to accomplish this.Thanks in advance!
The easiest way may be to use a spectrum analyzer with a magnetic field probe. This will accomplish what you are trying to do as you have described. As far as I know, there isn't a simpler way to do it with an ohmmeter as you want to do.
