Abstract
In use in a battery, a first spiral-wound battery element and associated wiring generates a first magnetic field and a second spiral-wound battery element and associated wiring generates a second magnetic field. The first element, the second element and the wiring may be arranged within a casing so that the first magnetic field is proximate to the second magnetic field and oriented in an opposite polarity. Conveniently, it may be shown that the total magnetic field generated by the battery has significantly lower magnitude than the total magnetic field generated by a conventional battery for the same current drain and same wiring structure.
