Large Powerful Magnet For School Project


Kabaka

Recommended Posts

I hope you can help me.  Years ago I saw a science fair project that had a large powerful magnet.  The magnet was held up about two feet over the surface.  A piece of string was attached to the surface with an piece of iron tied to the other end.  The magnet was powerful enough to pull the piece of iron straight up, the entire length of the string.  There was a bout a foot gap between between the magnet and the piece of iron.  It was really cool looking.  Anyone know where I can find such a magnet?  Thank you.

Just build an electromagnet - you can build enormously powerful magnets.

And you can turn it off.  That's a huge safety plus for a particularly strong magnet.  You can also control the field strength.  Should be lots of info on the web on what it takes to build one.
