An apnea monitor for adults consists of a flexible coil that wraps around the chest as shown in (Figure 1) . When the patient inhales, the chest expands, as does the coil. Earth's B-field of 5.0 × 10−5 T passes through the coil at a 53∘ angle relative to a line perpendicular to the coil. a)Determine the average induced emf in such a coil during one inhalation if the 260-turn coil area increases by 42 cm2 during 2.0 s.
