This so-called algebraic convention supports arithmetic comparison of north and south polarity values, where the relative strength of the field is indicated

by the absolute value of B, and the sign indicates the polarity of the field (for example, a –100 G field and a 100 G field have equivalent strength, but

opposite polarity).
