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). Reference to the magnetic field polarity is with respect to the beveled face of the device.

Maximum voltage must be adjusted for power dissipation and junction temperature, see Power Derating section.
For V

Magnetic flux density, B, is indicated as a negative value for north-polarity magnetic fields, and as a positive value for south-polarity magnetic fields.
