Several studies using SwISs ráilway workers have shown that exposure to time-varying magnetic fields with a frequency of 16.7 Hz, used in the Swiss railway system, can cause a significant decrease in melatonin production in the human body, which can then disrupt the circadian cycle and can also increase the incidence of leukemia in the exposed subjects. In one study, the careful measurement of magnetic fields at various heights at the location of the locomotive driver's seat detected an average magnetic field of magnitude 19.6 pT at the seated driver's head, 125 cm above the floor of the driver's compartment. The source of this magnetic field was found to be a power line that connected the 15 kV to 0.600 kV transformer, located at the front of the engine, to the electric motor located in the rear. If the power line connecting the transformer and the motor is a single cable 12.4 cm in diameter, including its insulation, running directly under the driver's seat and just below the floor, what is the current (in A) in the power line that will produce the measured magnetic field?

Ferromagnetism

Ferromagnetism is a mechanism by which some materials show magnetic properties. Iron and magnetite, an oxide of iron, are two naturally occurring materials that show the property of ferromagnetism. The word ferromagnetism is derived from the Latin name of iron, "Ferrum" as it was the first observed material to show such property. The property of ferromagnetism is shown by only a few substances such as iron, nickel, cobalt, and their alloys. Some transition metals and alloys of rare-earth metals also show ferromagnetism.
