When to use Van Allen Belts 3D Explorer

Use this explorer when you want to see the two trapped-particle radiation belts themselves, and skip it when you want Earth's magnetic field shape, which is a separate explorer.

Showing the real altitude ranges of the inner (proton) and outer (electron) belts
Explaining why the two belts drift around Earth in opposite directions
Introducing the South Atlantic Anomaly and why satellites get extra radiation there

This is an educational visualization with compressed sizes, particle counts, and drift speed.

Walk the controls in the step-by-step guide, or compare options in vs alternatives. Open the Van Allen Belts 3D Explorer.

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.
