Applied Magnetic Field
1. Large magnetic fields CANNOT damage NVE sensors.
2. 1 Oe (Oersted) = 1 Gauss in air = 0.1 millitesla = 79.8 A/m.
3. TCOV is the percent change in voltage signal over temperature with a constant supply voltage.
4. Resistance is specified with the saturating magnetic field applied.
