Method and apparatus for restoring or enhancing an ambient magnetic field

Apparatus and method are provided for enhancing the earth's dc magnetic field ( 14 ) and/or for restoring the earth's dc magnetic field ( 14 ), when the earth's dc magnetic field ( 14 ) has been degraded by steel construction, or has been degraded by either an extra-low-frequency or an rf magnetic field ( 96 ), in a living space ( 144 ). Magnetic-field enhancing/restoring apparatus includes beds ( 120 ), mattresses ( 314 ), bassinets ( 428 ), other seating furniture ( 370 ), office furniture ( 414 ), rooms ( 186 ), buildings ( 222 ), child-restraint seating ( 560 ), and vehicles ( 712 ). Apparatus and method also are provided for enhancing the earth's dc magnetic field in a body member ( 608 ) by use of body-worn apparatus ( 596 ). Magnetic-field enhancers/restorers include magnetic-field-enhancing coils ( 226 ) and magnetized sheets or pads ( 514 ).
