"This superconducting magnet can do more than attract paper clips. It could unlock energy sources that could free humans from fossil fuels. And you are about to take this miracle of science and ...

We're going to use a paperclip, three differentmagnets and a ruler to measure the distance each time. The greaterthe distance that the magnets attract the paperclip, the stronger themagnet.

Metal paper clips contain iron, a metal that magnets attract. Magnets can work through many materials, including paper. The wonder wand magnet attracts the paper clips through the paper, allowing the ...

The paper clips, jar lid, and nail are probably magnetic ... But some metals are magnetic and some are not. The metals that are magnetic (attracted to magnets) are also the metals that can be made ...

and watch it pick up paper clips or other ferrous materials. It is also grade school science to show that neither an electromagnet nor a permanent magnet will pick up nonferrous items like copper ...
