Please School Me On Electric Motors

The best analog I can think of is a paddle wheel on a boat. There is always some slippage, but it still moves the boat forward.
 
Ok, am I correct that the induced magnetic field in the rotor follows the stater field, and is not in one physical spot on the rotor?
 
Sort of, the rotor has "conductor bars" spaced evenly around it which "grab the flux" so to speak and turn it. Very layman's here but that's essentially it.
Jim's description is a good one- like a paddle wheel, always slipping some.

Thankyou I'm good with mechanical and basic electrical stuff, but electronics throw me in a tail spin.
 
Another good example of slip is watching a V-belt travel around a pulley with a strobe light.
