Relative values of B use the algebraic convention, where positive values indicate south magnetic polarity, and negative values indicate north magnetic
polarity; therefore greater B values indicate a stronger south polarity
fi
eld (or a weaker north polarity
fi
eld, if present).

The range of values speci

Relative values of B use the algebraic convention, where positive values indicate south magnetic polarity, and negative values indicate north magnetic
polarity; therefore greater B values indicate a stronger south polarity
fi
eld (or a weaker north polarity
fi
eld, if present).

Measured without bypass capacitor between VCC and GND. Use of a bypass capacitor results in slower current change.
