You're shopping for a full-body PEMF mat, and the spec that jumps out is the coil count. More coils sound like more field. But a count is a headline, and it leaves out two things that shape what your body actually gets: whether the coils fire all at once or one at a time, and how evenly the field is spread across the surface. Two PEMF mats holding the same six coils. On the left, all six coils fire together. On the right, the coils are numbered one through six and fire one at a time, with only coil one…

Asked together, they replace marketing copy with a measured picture of what the device actually does. Question 1. Where was the peak measured? The reading depends on two things: how far the probe sits from the accessory surface, and where on the surface…

If you've ever stood in front of two PEMF devices, compared their published values, and felt like you couldn't tell which one was better, you're not the problem. The values are the problem.
