内容简介

Will a magnet pick up a paper clip or a feather?The answer is, just the paper clip. Magnets only pick up things that contain bits of iron. In this new addition to the Let's-Read-and-Find-Out Science series, veteran author Franklyn Branley explains the properties and behavior of magnets. True Kelley's charming illustrations will entertain readers as they discover for themselves what makes a magnet. Hands-on activities include making a magnet and compass.
