Electromagnet Information:

What did you learn from the experiment? I want to teach another 3rd grader what I learned.

I learned how to make a nail into a magnet. Would you like to know how? You need a battery and wire and  nail and a paper clip. So you wrap the  wire around the nail, then you attached the wires to the opposite ends of the battery. Now you have magnetized the nail and start picking up paper clips.

How does what you learned apply to a pinball machine?

I would put an electromagnet into my pinball machine so that it moves the steel ball. The magnetized nail could be used to hold the steel ball in a still position until the launcher strikes the ball to start the game.
