Don't be panic from the title - I guess it has minor effects on fishes than on human.
I used a newly purchased TriField Meter to check Electromagnetic pollution at home. The reading of magnetic field is high near my pc - confirm my doubt about it - about 6 milligauss (less than 3 milligauss is considered to be safe based on very preliminary research, and above 3 should be avoided for long term exposure,) but it reachs 100 milligauss on top of an old AC mini filter and 6 milligauss at distance of 2 feet.
Strangely, on top of a new AC 70/500 filter it reads 25 milligauss, and 3 milligauss at distance of 2 feet, although the AC 70/500 filter is bigger and more powerful than the AC mini.
The background magnetic field is high (4-5) around the floor where the tank using the AC mini stands. The position of the AC mini may also results a high reading - my guess but not sure.
My suggestion is when you watch your fishes, don't get too close to the filter and don't put the tank too close to your seat.
I don't have other filters to do test, and I still love my AC filters.
