available material? Here's my teacher's word-for-word description from the assignment sheet:
"The purpose here is not simply to build the most powerful electromagnet, but the most effective one. That means you have to think about the kind of metal you will use for your core, the thickness (gage) of the wire you use, how tightly you will make the coil and the shape. Be aware that you have to exercise caution in the construction of your magnet since a nine-volt battery can heat wire up pretty quickly.
"YOUR MAGNET MUST HAVE A SWITCH TO EASILY TURN IT ON OR OFF.
"The magnets will be demonstrated in class on 6/13/08. Magnets will be tested on their ability to lift iron or steel masses a certain height."
Please include information on what materials can I use and how much will they cost. Try to keep it under $100. Thank you.
If know any useful links to website that could help answer my question, please include those also.
