A flux sheet is the smart way to make otherwise invisible magnetic fields visible. How do flux detectors work? Small nickel particles collect and show a dark color where the magnetic field is strongest and at the same angle as the sheet. The light marks on the sheet show where the magnetic field is parallel to the sheet. The
