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 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…

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.
