Fields from Transit System
If Bonnie McKinnon reads this, the flux densities she has seen, with
15 mG at the house, are consistent with a three-rail transit railway [ no
overhead cables ] with a typical load of 1000 amps at a distance of 10
metres, thirty feet. This is a dc field and I know of no suggestion that
dc or slowly varying fields affect health. Draper et al were reporting on
ac fields from ac overhead power lines.
