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.

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.

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.

Excelente para mis clases de Magnetismo

I bought several of these for magnet science labs in my classroom and I’m very happy with the sets.

I don't know why but this was the only set available with those typical horseshoe magnet which I wanted, I bought the whole set which I didn't mind too much because the other pieces were fun, but this whole thing is extremely poor quality, the box latch was broken, the horseshoe magnet was broken as well.

My boy loves this plays constantly with it
