[edit]Figure 291 -- Formation of eddy currents in a solid bar inductor
(Paraphrasing for modern English)
In figure 291, a solid bar inductor on a rotating armature is just passing under the tip of the pole piece N of the field magnet. Note the uneven distribution of the lines of force across the bar inductor. The magnetic field is more concentrated and thus stronger on the left edge (a,b) while the field is weaker on the right edge (c,d). Since the two edges of the bar move with the same velocity, this difference in field strength across the bar creates whirls or current eddies within the copper bar.

{{vector version available|new image name}} .
It is recommended to name the SVG file “Hawkins Electrical Guide - Figure 291 - Formation of eddy currents in a solid bar inductor.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
This technology 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 After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag.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. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}.
