From: Highly compliant planar Hall effect sensor with sub 200 nT sensitivity
Detection of magnetic stray fields. a A compliant PHE sensor is wrapped around a copper wire with a radius of 1 mm. White arrows represent schematically DC current pulses in the wire. b Finite element simulations reveal a density plot of the magnetic flux, generated by the wire upon applying DC current pulses of 100 mA. c A profile of the magnetic flux density from the wire surface indicating an intensity of 20.4 µT at the sensor location. d Transverse voltage measured by the sensor, clearly separating the incoming current pulses of different polarity
