In this chapter, readers see how Marie and Monique want to make the strongest magnet possible and had various ideas for how to do so. They wonder whether the number of times you stroked the tube made a difference. They wonder whether the size of the filings made a difference. They wonder whether they could magnetize the filings by putting the tube in an electromagnet. They wonder about other possible features. But they were stuck. How were they going to measure the strength of the magnets they made? This sample chapter also includes the Table of Contents, Be Safe, and Index.
