This image could be re-created using vector graphics as a SVG file. This has several advantages; see Commons:Media for cleanup for more information. If a SVG form of this image is available, please upload it and afterwards replace this template with
{{vector version available|new image name}}.It is recommended to name the SVG file “Schematic-of-a-tokamak-chamber-and-magnetic-profile.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
 | This image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans.

Summary
| Description |
English: Schematic of a tokamak chamber and magnetic profile. A tokamak is a doughnut-shaped vessel with armoured walls that can confine a hot plasma under high vacuum. It does this using a combination of magnetic fields to guide electrically charged particles: “toroidal” (blue arrow) and “poloidal” (green arrows) fields create a total field that twists around the torus in a gentle helix (purple). The poloidal field is generated by a toroidal current in the plasma, which is produced by a transformer that induces a current in the toroidal direction. With JET, this current has been as high as 7 MA and it will reach 15 MA in ITER. The toroidal magnetic field is provided by external, poloidally wound coils and is typically 10 times stronger than the poloidal component. |
