Sometimes with great difficulty.
Heat the end plate to say 150 degrees and bump it over something with a clearance hole for the cam ring.  It may take a few goes, depending on the amount of corrosion around the ring.

Probably not a manual one I'm guessing, as they move easily as a rule. But the fixed ones can be hard. A neat and easy-to-make  weapon for getting two-lobe camrings out is shown here: http://www.brightsparkmagnetos.com/workshop/BitsAndBobs/index.htm

Cam ring successfully removed  *smile*

I soaked it in WD40 and left it for an hour or so, then I used a large flat blade screwdriver moving around the edge and slowly tweaked it out.
