Magnetic
fl
ux density, B, is indicated as a negative value for north-polarity magnetic
fi
elds, and as a positive value for south-polarity magnetic
fi
elds.
This so-called algebraic convention supports arithmetic comparison of north and south polarity values, where the relative strength of the
fi
eld is indicated
by the absolute value of B, and the sign indicates the polarity of the
fi
eld (for example, a –100 G
fi
eld and a 100 G
fi
eld have equivalent strength, but
opposite polarity).
