How to extrude concentric 2D circles without forming only one 3D solid, but rather make different solids?

I am trying to extrude concentric circles, but if I select them all and extrude them, the extrusion makes a single body. I also tried with different sketches and it is the same issue. Is it possible to extrude each circle and form different objects? Something like a Swiss roll.

Yes. The trick is to make each cylinder of the roll it's own individual extrude, and to un-check 'merge result' for each new extrude.

Unchecking 'merge result' is what allows multiple part 'bodies' to exist in a single part file.

During Extrusion you have a Chance to select specific 'contour'. Click over there and choose the contour of your choice.
