SUMMARY

The discussion focuses on the behavior of magneto-resistive sensors when subjected to Earth's magnetic field rotation. Specifically, it addresses the need to sketch the voltage output of such sensors during a 360-degree rotation, assuming a zero horizontal magnetic field component. Participants emphasize the lack of readily available resources detailing the transfer function of magneto-resistive sensors, highlighting the necessity for reliable references in academic assignments.

PREREQUISITES
  • Understanding of magneto-resistive sensor principles
  • Familiarity with Earth's magnetic field characteristics
  • Knowledge of voltage output characteristics in sensor applications
  • Basic skills in sketching and interpreting sensor output graphs
NEXT STEPS
  • Research the transfer function of magneto-resistive sensors
  • Explore the effects of Earth's magnetic field on sensor output
  • Study voltage output characteristics of various sensor types
  • Investigate academic papers on magneto-resistive sensor applications
USEFUL FOR

Students in physics or engineering fields, researchers studying magnetic sensors, and professionals involved in sensor technology development will benefit from this discussion.

Hi!

um, i have a problem with my assignment. (don't worry, I'm not asking for the whole thing to be solved here!). and basically i have to sketch the voltage output of a magneto-resistive sensor when it's placed in Earth's magnetic field and rotated 360 degrees. the horizontal component of the field is assumed to be zero. i have trawled the internet for information and found none. does anyone know a site which will provide this information? well, i don't mind a direct answer but i need to reference everything!

thank yooouuuuu :blushing:

So when you googled magneto-resistive sensor, and read through the hit list, what did you find for specific information about the transfer function of the device?
