I need to make a powerful electromagnet that I can plug into a normal 120 volt outlet. Any suggestions?

The more powerful the better.  Also, try to make the answers simple and straightforward if you can.  I don't know very much about electromagnets thanks.

Well, the AC power will put a huge damper on your magnets power, the reason being is that as the magnetic field switches, the magnetic domains in whatever your lifting will not be able to keep up (assuming that your core does), making it so whatever your lifting will be repelled for a short time before it sticks. also the magnetic field completely collapses before it switches polarity, making it so its actually pulling in pulses rather than constantly. you would be able to lift more with the same magnet using 30 volts in DC power What I recommend is buying a FULL WAVE BRIDGE RECTIFIER, causing the AC power to switch to DC.
First thing, you can't do it with an AC supply.
Why not?  I mean, why not drive alternating current through some wire, and get an alternating magnetic field?  

Dog didn't give us much to go on, except the specification that  this magnet be "powerful".

Yes, it can be done, but how does depend upon what you want it for.
Would it stay put in one place, what does it need to hold/magnetise etc?
