Still trying to wrap my head around what is being proposed.......that traps are magnets.......and means to measure the magnetic force.......a magnetometer.
So I looked up "magnetometer" and came away with more questions than answers.
https://en.wikipedia.org/wiki/MagnetometerWhich of the various types of magnetometers are being suggested to be used? As in which product.......exactly. There seems to be many forms.
If a magnetometer is the tool to measure the strength of the magnetic force inherent in the magnet......the trap......how does the trap get magnetized in the first place?
To answer you the best way would be to repeat what’s already been said. If you will go back and read all of the post that I made pertaining to magnetic fields or radiation off of a trap or a trap device. You can find all of the post under users post on Trapperman.
Don’t think of magnets or magnetism you’ll get confused. All you are doing is measuring the intensity of the positive ions radiating off of the traps and devices. Negative ions will always give you a reduced field and the positive ions a more intense field.
Negative ions are good positive ions are not good at high levels or higher levels than the average induction of the earth
