Several coronal bright points identified in a quiet region of the Sun from Solar and Heliospheric Observatory /Extreme-Ultraviolet Imaging Telescope Fe XII images are found to have a time evolution from birth to decay that is extremely well correlated with the rise and fall of magnetic flux as determined from photospheric magnetograms made with the SOHO /Michelson Doppler Imager instrument. Radiative losses of the bright points are found to be much less than conductive losses, but the sum of the two is comparable with the available energy of the associated magnetic field. Several small "network flares" occur during the lifetimes of these bright points, emphasizing the strong connection of such events with the magnetic field.
