I want to measure magnetic fields with my oscilloscope, so I need a magnetic field sensor / probe.
My oscilloscope does a FFT for 50Hz to 2MHz.
The sensor should be 3D, because I don't care for direction. The sensor should be sensitive enough for measuring human exposure at computer workstations.
I have read that a Hall effect sensor should do this and is fairly easy to drive, which would explain why I haven't found any good ready to use sensors in the internet.
My search coil tends to be very sensitive at 590KHz, maybe an article about search coil calibration would be helpful.
When choosing a Hall effect sensor,
- Do I have to consider my frequency range (50Hz to 2MHz?)
- Are all Hall effect sensors sensitive enough for measurements of human exposure at computer workstations (60cm to CCFL screens?
