Iphone and Android question - Ron - 02-28-2020
Dear Friends,
I would REALLY appreciate your feedback on the below:
1. How can I know what frequencies the iphone 10 or in general typical smartphones can detect using the magnetometer?
What frequencies? What wavelengths in centimeters?
2. How would/could we use the magnetometer as a "telescope" to observe space and determine structures of planets and their composition?
(I have some ideas - and would love to hear yours!)
Thanks,
Ron

1. This sounds like you are thinking of the wrong order of magnitude. The magnetometer typically samples at rates around 50 Hz to 100 Hz. In contrast, electro-magnetic waves with cm wavelength are what we call micro waves with frequencies in the range GHz (i.e. 1,000,000,000 Hz). A electro-magnetic wave with a frequency of 50 Hz has a wavelength of 6,000 km = 600,000,000 cm.
2. No idea. Is there a context to this question?
