Based on my observations, this magnetic kit is a great investment for any science classroom or curious individual. The iron filings provided in the container are high-quality and perfect for conducting countless experiments related to magnetism. The magnetic pull of these filings is so strong that it made the experiment a hit in the class. Students were engaged and the kit helped us demonstrate magnetic attraction and repulsion with ease. The kit is perfect for industrial and scientific use, be it in the classroom or professional setting.
