The Giant Magnetoimpedance (GMI) effect refers to the strong and sensitive
change of impedance of a magnetic conductor with a small variation in the DC
Even though an RVmagnetics MicroWire sensor is a magnetized element, its permeability is ~ 1, like in a
vacuum. This enables the sensor to operate in heavily magnetized environments,
to provide measurements on the magnetic field , and at the same
time to not have biased measurements from the effects of the heavy magnetic
environment. Although MicroWire is a magnetic sensor it does not work
with GMI effect, it works with audio frequencies.
