Part 2: DAQ practice . Determine the magnitude and direction of the magnetic field at your lab table using a mobile app (e.g., PhyPhox). . Determine the magnitude of a nearby magnet's field (like an earbud), subtracting for the room's field. Note: subtracting vectors is different than subtracting scalars. . In your Lab 1 submission, include a screenshot of the magnetometer readout and your group's calculations. Part 3: Analysis practice . Export a set of magnetometer readings to a spreadsheet (e.g., Excel, Google Sheets, Numbers) o Create a histogram of the magnetic field's magnitude values o Calculate the mean and standard uncertainty of the field's magnitude values (see the Holmes' Statistics Summary sections 1 & 2) Use a Jupyter notebook to repeat the spreadsheet analysis in Python. Here's a template. histogram. . In your Lab 1 submission, include your group's spreadsheet histogram and Python histogram
