This magnetic field sensor app measures and displays a graph of Magnetic Field (µT) vs. Time (s) that in x, y, and/or z dimensions, as well as total magnitude. By accessing settings, data can also be displayed with a digital read-out. Total magnitude magnetic field strength can be recorded and exported in an e-mail or through Google Drive as a .csv attachment using a comma or a semicolon as a delimiter. Click on settings to plot data against elapsed time or clock time, to change the plot line
