Plot 1. Transfer function at the exact sensor location. Excitation
coil is not part of cancellation system.
Sensor is the magnetic flux gauge
and it is part of cancellation system.
Plot 2. Transfer function in the volume of 0.5 x 0.5 x 2.5 feet.
Excitation and sensor coils are NOT part of
cancellation system. Excitation
coil positioned outside Helmholtz cage, sensor coil is positioned
near
magnetic flux gauge and has dimensions of 0.5 x 2.5 feet.
