Help your students become magnet “experts.” In this hands-on introductory kit, students experiment with bar magnets to visibly see why magnets “stick” to certain objects but not others. They test magnetic polarity and determine what types of materials are magnetic. Lastly, students sprinkle iron filings over the magnets to display the invisible magnetic fields that surround all magnets and see how the magnetic fields are bent when two magnetic north poles repel and when north and south poles attract. Includes detailed laboratory instructions and background information. All materials are reusable.
