Chapter 31, Problem 10P
Scientific work is currently under way to determine whether weak oscillating magnetic fields can affect human health. For example, one study found that drivers of trains had a higher incidence of blood cancer than other railway workers, possibly due to long exposure to mechanical devices in the train engine cab. Consider a magnetic field of magnitude 1.00 × 10−3 T, oscillating sinusoidally at 60.0 Hz. If the diameter of a red blood cell is 8.00 μm, determine the maximum emf that can be generated around the perimeter of a cell in this field.

- True or False A moving charge entering a magnetic field parallel to the field will move in a straight line. A man whose resistance is 10,000 Ω has 120 volt potential difference across his body. This would cause a fatal shock. Adding resistors to a parallel circuit decreases the equivalent resistance.
