surveys and monitoring. Active magnetic field cancellation.
Ametes Three-Axis Magnetic Field Sensor. Three Sentron CSA-1V with sensitive axes mutually perpendicular. Three analog output signals for Bx, By, and Bz.
Ametes Three-Axis Magnetic Field Demonstrator. Self contained instrument used to demonstrate and
monitor the output voltages from the Ametes MFS-3A 3-axis Magnetic Field Sensor.
Conversion
of gauss to tesla:
1µG = 0.1nT, 1mG = 100nT, 1G = 100µT,
10G = 1mT, 10,000G = 1T
Relationship between Magnetic
Flux Density (B) and Magnetic Field Strength (H): In vacuum (or air) B=µoH.
For SI units µo = 4pi x 10-7H/m,
B is expressed in Tesla and H in Ampere turn/m or
A/m. Hence in vacuum or air a flux density of 1T
= 796kA/m.
For cgs units µo = 1, B is expressed
in gauss and H in oersted. Hence in vacuum or air
a flux density of 1 gauss = 1 oersted.
