Milky magnets makes marrow more meaty :P
Yes - there are magnets in the motor assembly. It's what makes the motor turn.
(electro) Magnets in the "track".
Yes, magnets can lift up objects that are attracted to them. The strength of the magnet and the weight of the object will determine how well the magnet can lift it.

Slot cars use magnets that help hold the cars on the track
Most cars do not use many magnets, however, there were several experimental cars developed during the 1940s and being reexamined currently that actually run on large electromagnets. The main downfall of these cars is that they pulled down power lines and literally ripped cables up from under the road with their powerful magnetic field.
