When to use Sunspot Magnetic Loops 3D Explorer
Use this explorer when you want to see the magnetic structure over a sunspot region - and skip it when you want the 11-year sunspot count cycle or the Sun interior layers.
- Classroom demos of coronal loops and bipolar sunspot pairs
- Connecting the umbral field strength to why sunspots are dark
- Showing that loops trace invisible magnetic field lines
This is an educational visualization with illustrative loop shapes and stylized plasma flow.
Sunspot magnetic loops key figures
Sunspot magnetic loops key figures in one panel: Sunspot Magnetic Loops 3D Explorer lists umbral field 2000-3700 gauss, umbra ~3700-4000 K, photosphere ~5800 K, and coronal loops at 1-3 million K.
| Quantity | Value |
|---|---|
| Umbral magnetic field | 2000-3700 gauss (0.2-0.37 T) |
| Umbra temperature | ~3700-4000 K |
| Photosphere temperature | ~5800 K |
| Coronal loop temperature | 1-3 million K |

Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
