Many of our readers probably remember certain scenes from Iron Man 3 in which Tony Stark puts on his armor as if it were magnetized. That gets him into trouble several times, but the billionaire-philanthropist-superhero ends up mastering that ability (more or less), although in general terms it doesn't do him much good. Now, the truth is that anyone interested can create a similar effect using neodymium magnets, and if they decide to film the magnetic collisions in slow motion, well… let's just say the end result isn't bad at all.
Neodymium Magnets: Handle With Care
The entire Web warns that we must be careful with neodymium magnets. Their size does not fully represent the power of their magnetism, and any unwary user can end up seriously injured. At the same time, many of these magnets have a fairly affordable price, which makes them ideal candidates for simple DIY experiments. In early February we observed the behavior of neodymium magnets on copper plates, but there is something more impressive to see: collisions between them...
The Slow-Motion Video
The slow-motion video published by the Magnetic Games channel on YouTube reveals the spontaneous reaction of the magnets, and in some cases, the force of the impact. A trained eye will probably notice that some magnet pieces fly off due to the intensity of the contact, which serves as a warning in case we try something similar at home. Another success of the video is that at the end it shows us the magnets in real time. My personal recommendation for headphone users is to lower the volume a bit, because the noise of the collisions is likely to take you by surprise (and no, the audio isn't malfunctioning; the pops and clicks are the result of the hits, distorted by slow motion).

And yes, this reminds us in a certain way of Tony Stark… the Tony Stark of Iron Man 3 who puts on his armor by force, and the real-life Tony Stark (i.e., Elon Musk), who beyond his Tesla Model 3 setbacks, has seen great advances in terms of making holes in the ground with his Boring Company, and the development of the Hyperloop, which has a close relationship with magnetism.
