Comment on Ask HN: Need to generate a magnetic field with a Pi Zero WparentComments−nblavoieOP8yThank you for your feedback. Correct me if I'm wrong, but the magnetometer is only for measuring the earth's electromagnetic field, right ? What if I want to detect metal nearby, does the same chip will be OK for the task ?−oblib8yNo, it will detect a nearby magnetic field. I had to try that just for fun when I had mine hooked up.
