Is there a machine or force that can reverse the effects of a centrifuge?

Hey all, first post here on PF.

This might be a stupid question, but I haven't been able to find if there is a machine that does the opposite of a centrifuge, specifically forcing material into the center of a circle. Or if there is a force that is reproducible on a small scale that does this.

Again, sorry if this is silly, but I'm thinking of making something and this is kind of crucial!

Thanks!

Seems to me you could use a centrifuge that has capsules at the end of it. The heavier material is forced into the center bottom dome of the capsule.

I can think of two examples:
1) Using high explosives (ie Nuclear Bomb ignition)
2) Using high energy lasers to detonate the surface of a fuel pellet (ie Fusion research)

If you have a particular application in mind it might be easier to come up with something more practical?

It depends on how much stuff, how quickly, etc.

A funnel forces everything to the center of a "circle".

Dang, how'd we miss that one!? D'oh!

EMF in a ring around the substance you want pushed to the center.

A centrifuge does it... The lighter material moves toward the center. ;-)
