Breathing monitor An apnea monitor for adults consists of a flexible coil that wraps around the chest (Figur e P18.23). When the patient inhales, the chest expands, as does the coil. Earth’s u B field of 5.0 * 10-5 T passes through the coil at a 53° angle relative to a line perpendicular to the coil. Determine the average induced emf in such a coil during one inhalation if the 300-turn coil area increases by 42 cm² during 2.0 s.
