For competition horses, the FEI caps PEMF field strength at 1,000 Gauss. Here's what the limit means, and how a certification shows which device-and-accessory pairing stays under it.

Frequency is one of the few PEMF specs you can actually use, once you read the band name for what it is: a pulse rate, separate from strength and from the pulse edge. Here's what it tells you, what the devices we've measured actually run, and how to use it.

On a single device, swapping the coil changed the peak field from 22,410 to 8,670 Gauss, and the lower-peak coil put out nearly twice the total field. The accessory, not the device, sets what you get.

Rise time, fall time, and slew rate describe what a PEMF pulse does in its few microseconds. Here is what each one means, measured on a real device.

We bought a Sota Magnetic Pulser and put it on our instruments. Here is its real measured output: peak field, slew rate, field reach, and pulse rate, at each setting.

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.

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.

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'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…
