How PEMF works comes down to a changing field, not a strong one.
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.
Now you can see the field your device actually makes, in 3D.
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.

How to convert Gauss to Tesla, and why a Weber figure won’t convert.
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…
Two discs can look identical from the outside, but the coil wound inside sets the field’s shape.
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…
Two reports just became one to make it even easier to see how your devices and accessories are performing.
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…
A donut disc looks just like a pancake disc, but its field peaks in a ring, not at the center.
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…
A pancake coil is strongest at the center. An inch off-target cuts the strength in half.
When you place a disc on a knee for a 40-minute session and the patient feels less relief than expected, the instinct is to blame the device. Placement is the more likely culprit. A brochure can list peak Gauss without saying where the field is strongest. That value alone doesn't tell you where to place the disc. Two discs of the same outer size can deliver very different fields. A pancake coil peaks at the center; a donut coil peaks in a ring around the center. A cross-section of a pancake coil drawn beneath a field-strength curve. The spiral winding…
A smaller peak Gauss value can induce more in tissue. Faraday’s law explains why.
A smaller peak Gauss value can induce more in tissue. Faraday's law explains why. Two PEMF devices sit side by side on a shelf. One brochure says 7,000 Gauss. The other says 1,500 Gauss. The bigger value looks like the obvious winner. Faraday's law explains why it sometimes isn't. Tissue inside the body doesn't respond to the strength of a magnetic field. It responds to how fast that field is changing. A short, sharp pulse from a lower-peak device can induce more electrical activity in tissue than a tall, slow pulse from a higher-peak device.
