Scientific work is currently underway 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 0.00100 t, oscillating sinusoidally at 68.5 hz. if the diameter of a red blood cell is 6.00 µm, determine the maximum emf that can be generated around the perimeter of a cell in this field.

Athin, square metal plate measures 14 cm on each side and has emissivity of 0.60. the plate is heated to a temperature of 745°c. what is the rate at which the plate radiates energy ? the stefan-boltzmann constant is 5.67 × 10-8 w/(m2 ? k4). remember that the plate will radiate energy from both its top and bottom surfaces.
