Metal powder that makes invisible magnetic fields visible.
The metal powder box is a simple but effective educational tool for teaching and exploring magnetism. This compact container contains iron powder that reveals magnetic fields when exposed to magnets, transforming invisible forces into visible, observable patterns.

For classroom demonstrations or home learning:

• place a magnet under paper or plastic, place the box on top, and watch the students’ eyes light up as the field lines appear instantly.
• test different magnets to compare their magnetic fields.
• illustrate abstract concepts such as poles, field lines, and magnetic force in a tangible way.

Iron powder clearly shows where the magnetic forces are strongest and weakest. Children can see how the field lines orient themselves from the north pole to the south pole and observe patterns of attraction and repulsion. This direct observation makes the physical principle easier to understand for students from kindergarten through high school.

Features:

• Convenient container for storing iron powder and keeping it ready for use.
• The fine powder particles react instantly to magnetic fields.
• Reusable for countless experiments.
• Works with any standard magnet.
• Suitable for all ages and learning levels.
• Taille: 2″ x 2 3/4″ (5 x 7 cm)
