How do you release the wire from a fluorescent tube lamp holder?
Where the wire is held in the holder you will see a small round hole. Insert a small nail into it and push inward. This will release the spring that holds the wire. Pull on the wire and it will come out. Now you can release the pressure on the small nail to let the internal spring return to its original position.

How do you magnetized an iron rod Picture?
Graphics can't be shown on Answers.com. Take a large iron nail (or several nails, 6 inches long). Wrap several layers of thinly insulated wire round the nail(s), and connect the bared ends of the wire to the positive and negative terminals of a 9 volt battery. As the electrical current is sent through the coiled wire, the iron nail(s) becomes electro-magnetised and will attract metal. Turn the current off, and the metal will drop off, for the nail(s) are no longer magnetised.
When you make a homemade electromagnet with wire and a nail and a battery does stripping the wire that is coiled around the nail make the electromagnet stronger?
No, this will stop the magnet from functioning and is the same as using a short thick wire instead of a long coiled wire.

What are the holes on the back of the outlet?
What's the question? The holes on the back of the outlet are for inserting the wire and to release it so you can pull the wire back out. There should be a round and a rectangle one for each side terminal. They only accept 14 gauge wire, not 12 gauge. Older one would accept both, but not for several years. Wire goes in the round hole and you insert something such as a small nail in the release hole and push in and then pull the wire out. The outlet will have a strip gauge on the back if the holes are for self holding lugs, and a square or round release next to the hole. You don't have to hit the release when inserting wire,only removing it. If the outlet is rated 120v, 15 or20 amp,it will hold 12ga wire.
