I was going to mention centripetal force here but decided to do some research first: https://physics.stackexchange.com/questions/109500/does-cent...

Turns out that centrifugal force "does exist" in side the rotating reference frame. As if, your looking down on the object rotating around a center, the only force there is centripetal pointing in and Inertia pointing tangent to the circle. However if you enter the reference frame of the object being flung around you lose the inertia term since your already the center of the system and then need a centrifugal term to make up for that.

So in reference to _being_ on a hamster wheel, the outward sensation could be attributed to a centrifugal apparent force.
