Electromagnetic attraction

The site in exasperating to use. I tried to past my question but it doesn't work either, so I attached it. Please let me know. Thanks.

Games you can play with a bolt some wire and a nib magnet.

any ferrous (iron containing) metal will do. So, yes, thats anything attracted to a magnet. If memory serves, soft iron is best. Usually, a bolt, nail, or bundle of nails works well. Check my -ible "monkey hunter" for 1 way to do an electromagnet.

It doesn't seem to have attached. Argh! :-(

I'll try to paste again:
"I'm going to be making an electromagnet and read up on how to make one, which is pretty easy, by basically just winding a wire around a magnetic material core and connecting some electrical power to the wires - low volt DC will do.

As I understand it, just the wires wound into a coil will create a magnet by itself but adding the core into the coil increases the magnetic force. I think even a tube can be used as a core.My question is about the material of the core.

I want to know which materials are best for the core material. I'm not interested in creating a permanent magnet with the materials. Is there a comparison chart of say, the top 10 materials with the most magnetic attraction and how is that measured?Also to clarify, with the coiled wire conducting electricity around the core, is the electromagnetic function specific to the core about that the core needing to be a magnetically attracted or of electrically conductive material - or both?

Thank you!"

Finally the paste worked ...
