See the shape of a PEMF field, not just its peak.
A spec sheet gives you one number, the peak. A coil produces something more significant: The actual field. It rises off the coil, spreads out, and fades with distance. Where the field is strongest depends on how the coil is wound. The views below let you see It from every angle
We include this with every Certification Report using data we collect while testing your device and coil so you can see exactly how the field looks on your product
Interactive 3D field volumes measured by Gauss Labs, one for each common coil type. Pick a coil type, then drag to rotate and scroll to zoom the real measured field.
A ring-shaped coil. The field peaks in a ring and dips over the hole in the middle.
How to read the views.
Drag to rotate, scroll to zoom, and step through the layers to watch the field reach out from the coil and fade. Each view is a different common coil type, so you can set them next to each other and see how differently the field is shaped from one to the next. These are illustrative examples of each coil type, not a spec for any one product.
Four coil types, four field shapes.
- Loop coil. Wire wound into a single open ring. The field is strongest over the wire and dips through the open center, so a loop suits a broad area or a limb more than one small spot.
- Pancake coil. Wire wound into a flat spiral that runs all the way to the middle. The field is strongest at the center and falls off toward the edges, which makes it a focused choice for a small target.
- Donut coil. Wire wound into a flat ring with an open middle. The field peaks in a ring and dips over the open center, so its strongest field sits an inch or two out from the middle.
- Multi-coil mat. Many small coils built into a pad, each producing its own field. Together they cover a large area, and how evenly they cover it depends on the coils' size, spacing, and how they fire.
Why we show the whole field, not just the peak.
A peak value is one reading at one spot. On its own it can't tell you where the field is strongest, how far it reaches, or how evenly it covers your target. That's why we measure the full field in three dimensions, so the shape is something you can see rather than a number you have to take on faith.
Want to see your own device measured this way?
We measure the full field of a PEMF device and its accessory in our lab, then report it in charts you can actually read. See a finished example, or tell us about your device.
