What Metals are Attracted to Magnets?

[jazzy28]

I am trying to make sure the information that
I have gathered is correct. My experiment was
done with an magnet measureing 2 inches square. I tested the magnet on household items such as: pizza cutter, butter knife, paper clips, coins, aluminum pan, alkaline battery, aluminum foil, fork and spoon. I found that the
aluminum foil, aluminum pan, fork, spoon, coins didn't attract to the magnet. However, the alkaline battery, pizza cutter, butter knife, paper clip and the 5lb hand weight did attract. In conclusion, I realized that if a metal has more valence electrons, there would be more attraction between the metal and the magnet. Please, Please let me know if I am correct. Is there any other scientific statements that I can add to my
findings. Please help!!
Thank You

It's not actually a question of (just) the number of valence electrons. Only certain materials are magnetic in the conventional sense. Try doing a google search on "ferromagnetism"; you'll find a lot more information on how magnets work.
