We don't rank devices as more effective by raw strength
UnconfirmedVendor charts often split PEMF into low intensity below 1,000 Gauss and high intensity from about 1,000 up to 50,000 Gauss, with the suggestion that stronger is more therapeutic. We use a strength boundary only to sort hardware, not to rank effect.
Why we leave it out
Published magnetic-field effects sit far below those numbers, mostly from a few Gauss up to around 100 mT, and researchers describe amplitude windows where more strength can matter less rather than more. The 1,000 Gauss line we use is a Gauss Labs and FEI classification, and real high-intensity devices top out closer to 1 to 2 Tesla than the 5 Tesla some charts cite. Strength changes how far a field reaches, which is geometry, so we report reach and leave the bigger-is-better claim out.
