Or more likely magnetic field.  
If say, a 10 lb object was suspended in a magnetic field created by two magnets that weigh 3 lbs each. If you measured the net weight of this assembly, would it weigh 16lbs, or 6 lbs?

16 lbs I do believe  
The weight would be transferred to the two 3-lb magnets via magnetic force (push).  
For every action, there is an equal and opposite reaction.

Yep. The full weight of all combined.

Take two regular magnets. Push the poles so they repel - you can feel that push on both sides, correct? Same thing.

Great! Thanks for the info. I would have bet that the weight added, as I knew no law of physics that would allow the weight to disapear. But physics can be tricky and not follow what one would think is common sense.
