The Influence of Incident Power on the Magnetic Fluid Sensor Sensitivity Based on Optical Transmission Properties

Table 1

Variation in sensitivity of the 200 μm magnetic fluid sensor at different incident power.

Incident power (mW)	Sensitivity decrease	Sensitivity increase	Sensitivity decrease	Sensitivity saturation
	magnetic field (Oe), decreasing proportion	magnetic field (Oe), increasing proportion	magnetic field (Oe), decreasing proportion	magnetic field (Oe)
