EUDAX Labs Junior Science Magnet Set for Education Science Experiment Tools Icluding Bar/Ring/Horseshoe/Compass Magnets

I’m a physicist who spent over ten years developing high-speed magnetically levitated flywheels. I just needed a marked color magnet so bought this kit for next day delivery. I noticed that someone had trouble levitating the spindle because a rubber band was missing (any small rubber band will work). But another thing to be aware of is that the 4 stationary magnets may not stay fixed in the base (with pole orientation all pointing the same direction). Slipping a couple sheets of paper when the magnets are pressed into the base will help tightly secure them (see photo). And the magnets need to all be pressed all the way down, at the same height. Also, playing around with the axial orientation of the magnets on the rotating spindle makes a big difference in the stability of the unit (rotor spindle magnets need to also point the same direction as base). I like teaching physics and think this is a fun little package for children to explore, and recommend it. An interesting “thought experiment” is to visualize the magnetic flux field lines (think of the orientation of the iron filings by the bar magnets). This helps to understand how the spindle stays levitated (by imagining the field lines); and why the spindle is only stable with one point fixed (the pin-spindle interface). Otherwise, the stationary magnetic suspension here is unstable.

This little kit really surpassed my expectations. We do remote learning and I needed a magnet before the next morning. Options were limited and although I was looking for a cow magnet, this kit looked interesting so I took a gamble. Despite the price, nothing in the kit is cheap. It comes with instructions for a few different experiments, which the kiddo thought were really cool. The horseshoe magnet is weaker than I would have expected, but the ring magnets stacked together seem to have the same amount of force as a small cow magnet. So glad we took a chance on this, it had what we needed and so much more. These will be a go-to for years to come.

Pretty neat magnet set that my 5 year old loved (it says 14+ on the box). Got it for him cause he’s curious about scientific experiments. The recommended experiments in there are good, he was able to set them up himself without much help. The only downside was that one of the ring magnets broke on first impact from a dining table. But there are a few of them in the box. Would recommend for kids with curiosity about magnetism or science in general

The Horse shoe magnet was broken on delivery, but my son has still had a blast playing and learning with this kit. The pieces are quite small, so not appropriate for younger learners that cannot keep objects out of their mouths. The circle magnets especially are the size/shape of candy.

Got this for a science kit and it worked just as needed. All the magnets worked and the students thought it was so cool. It was easy to use and fun for the kids to play around with. There are a good variety of magnets, a good value for the money and can be used for a range of experiment/uses. Only down side is there is a lot of little pieces...as to be expected.

Ideal para los niños. Mi hijo feliz 😄 por su regalo 🎁 ame . Trae varias cositas . Ami hijo le encanta y deja el cel a un lado para jugar aprender y admirar los imanes.

Absolute junk. The compass needle does not move at all. The other magnets in the kit are barely magnetized, as in will not stick to a refrigerator. You can easily with almost no effort push two like poles together. Not recommended.

I got this magnet set for a 9 year old boy - he loves it!! He spends time building and experimenting with the magnets. I would not suggest it for little kids - but even from 5 on up it is well worth the cost. And one interested in magnets this is a great beginning kit - lots of different items to do things with. He has a wonderful time with it.

Excelente material

Muy didáctico, lo utilizo para enseñar magnetismo a mis hijos

Son funcionales pero con muy baja intensidad magnética... no volvería a comprarlo.
