Joseph's electromagnet

Joseph is studying electricity and magnetism this semester.  We have a book and kit for each.  After finishing the magnetism kit, we wanted to do a more powerful electromagnet than what we could do with the kit. So, one trip to Ace hardware, and ...

It's pretty strong, and it makes sparks!  Joseph's pretty happy and looking forward to going through the next kit.

That's Gideon's foot in the picture.
