About this item:
Stays clear! Steel flings are sealed inside a mess-free, transparent viewing tray made of special scratch-resistant plastic that stands up to classroom use. Steel filings (cleaner than iron filings) ensure cloud-free viewing. Learn how a magnet’s invisible force field works—view it up close and manipulate it with your own hands! Explore the basics of magnetism (attraction, repulsion, polarity, and more). Compare and contrast the magnetic fields of a bar and disc magnet. Includes rubber-coated magnets (.75 inch disc magnet and 1 inch bar magnet)—that won’t cause scratching—and filing-filled tray measuring 3.44 inches in diameter. Ages 8+/Grades 3+

5.0 out of 5 stars Great For The Classroom!
Besides being a great fidget item for adults, it is perfect for helping students visualize the shape of a magnetic field. I end up giving these away to students, so when I come across one I buy a spare. This one works well, and comes with two magnets, a button and a bar. You can tell that they are polarized differently from each other. The magnets provided have a coating on them, which protects the plastic case from being scratched. Be aware, though, that rubbing uncoated magnets over the plastic case will scratch it. That is not a defect with this product at all. I paint all of my uncoated magnets that I wish to use with these plastic cased demonstrators. This is a decent product. Buy one for yourself and your kids!

5.0 out of 5 stars For the price, it can't be beat
The filings are just the right size for this demo and the yellow puck magnet works great, the plastic is more than clear enough, well worth it!!

The plastic scratched way too easily. Should be made of glass, maybe.

5.0 out of 5 stars Fun for all ages!
This was a purchase for my 9 year old son. We opened it and the whole family played with it for hours!
5.0 out of 5 stars Good science toy for children
I wanted stocking stuffers for my grandchildren at Christmas. The magnet is small enough to fit in a stocking. It comes with extra parts to use to show the power of the magnet. My grandchildren enjoyed playing around with them and seeing what the magnetic particles inside the plastic dome would look like with different situations. I would recommend this for an inexpensive scientific toy for children.
