Gauss Labs PEMF blog

A PEMF device works by pulsing a magnetic field on and off. It's the change, not the raw strength, that reaches your tissue, which is why a big Gauss number isn't the whole story. Here's the plain-English version.

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…

Sign in to the Gauss Labs customer portal and you can now see the magnetic field your device produces as a 3D shape you can spin around, then watch it pulse on your device's own measured waveform. It isn't a stock illustration. It's the actual field we measured in our lab, rebuilt into a shape you can look at. Animated 3D render of the Magnetic Pulser's magnetic field rising and falling on the Paddle accessory, driven by the device's measured waveform. The Magnetic Pulser with its Paddle accessory. The field rises and falls on the device's own measured pulse, time-scaled…

You're comparing two devices, and the spec sheets don't even agree on units. One lists Gauss, the next lists Tesla, and a full report might add a Weber figure too. Here's how to tell which values you can line up against each other, and which you can't. Two side-by-side panels. The left panel, flux density, shows a flat disc with a probe arrow pointing to a single highlighted point and the units Gauss, Tesla, millitesla, and kilogauss, with the conversions 1 Tesla equals 10,000 Gauss and 1 millitesla equals 10 Gauss. The right panel, total flux, shows the same disc…

You've seen the phrase on every lab's page and half the spec sheets in your category: calibrated equipment. It shows up so often that it has stopped meaning much. So what should it actually tell you? A four-link traceability chain read left to right. The first box, highlighted in amber, is the bench instrument, the gauss meter or oscilloscope that takes your measurement. An arrow labeled checked against points to a working reference of better, documented accuracy. Another checked-against arrow points to an accredited reference kept by a calibration lab. A final checked-against arrow points to a navy box, a…

You're looking at two discs the same size, and their peak Gauss values aren't close: the bigger one is over four times the smaller. It's tempting to read the bigger number as the stronger device. But both came off the same device. The coil inside the disc, not the device's power, set the peak. A disc is just a housing. The coil it holds might be a pancake, a donut, or another shape entirely, and from the outside two discs can look the same. What you can't see is the wire inside, and that's what shapes the field. Two measured…

To see how a device and its accessory perform together, you used to read two separate reports. Now you read one. The first examples are on our reports page this week. Two small report documents on the left merge into one larger report document on the right. The first small document is labeled Device analysis and lists the pulse: waveform, rise and fall, slew rate, frequency. The second is labeled Accessory analysis and lists the field: heatmap, coverage, symmetry, depth. An arrow points from both into a single larger document labeled Device and Accessory Analysis, one report per pairing. The…

You're comparing two devices. One lists 20,000 Gauss, the other lists 800, and the first looks twenty-five times stronger. It might be. It might also be weaker. Until you know what each maker measured, the two values can't be compared at all. This month we read the public product and testing pages of PEMF makers across the industry, from high-intensity coils to low-intensity mats, and logged how each one states its field strength. There is no shared convention. Most publish a single Gauss figure without saying how it was measured. A few publish a time-averaged value. At least one publishes…

You place a disc's center over a small joint, run the full session, and the relief comes up short. With a pancake coil, that's usually a placement miss. With a donut coil, the placement itself is the miss: you've aimed the field's weak spot at the joint. Two discs can share the same outer size and housing and still deliver very different fields. The coil wound inside sets the field's shape. A pancake concentrates its strength at the center. A donut spreads its strength into a ring and leaves a dip in the middle. A cross-section of a donut coil…

When your buyer reads the peak Gauss value on your spec sheet, they imagine that's for the entire surface of the accessory. They don't know that it's measured at one point, at one setting, directly on the accessory surface. Additional measurements let you show more of the accessory's characteristics in your documentation. A side-by-side diagram titled 'Peak Gauss alone doesn't provide the clarity needed to make an educated purchase.' On the left, under the heading 'On the spec sheet,' a gold block displays '7,000 G' as the Peak Gauss reading, called out as the highest reading at one point on…
