Ferromagnetic Pillar Calculations

  1. Jun 3, 2010 #1
    I'm doing a research project using sensors in mobile smartphones, mainly the magnetometer. After taking extensive measurements on some pillars, in a hallway, that seem to give off a high magnetic field, measured by the smartphone's magnetometer, I now want to compare these magnetic field measurements with a calculated magnetic field. I can only find information regarding current induced magnetic field, but what about ferromagnetic material already

    I'm having trouble finding information regarding how to calculate the magnetic field of ferromagnetic materials as i don't think this subject was covered in my engineering physics course. We can assume that these pillars are some kind of iron/steel product, but not exactly sure what its made of. What kind variable should i be focusing on in the calculations. Here is a picture of what the pillars look like. Any help would greatly be appreciated.
