Hi, like i said im working on my Seminarwork, but i met some problems. 1. Why are there most magnetoresive Senors build in smartphones, and which kind of the is build in. I cant find any of the sensormodels names build in Smartphones so I cant google some intel about them. I know about the AMR and GMR effects and how they work, but i found a lot of different kinds of MR-sensors. 2. Are SQUID-sensors used in Smartphones too? 3. Can the Magnetic sensor get broken by a too strong magnetic field? i think mine is broken. The compass still works fine, but SensorKinetics says my room has in X,Y,Z direction : 90,233,-633 micro tesla. is this possible without metal nearby ( 1m to my pc )? 4. Which Sensortyp and name is build in in an iphone 5 and 6? 5. can you please rate my english, because im trying to get better in it :)
ty for ur help and for your time even if you dont know the answeres or are not sure.
