Discovery UK digs into the How It’s Made archives for this brief look at the process that goes into creating traditional magnets. After melting a cocktail of various metals in an electrical induction furnace, the fiery metal is poured into sand molds, then cooled, separated, and charged with multiple electromagnetic fields.
THE BEST Magnets
A while back, YouTuber Mr. Michal showed off a simple railway he built from coils of wire, batteries, and magnets. Now, he’s back with a much longer and more complex train set that still operates on the same electromagnetic principles. This time, the track measures in at over 20 meters long, or about 66 feet.
These pentagonal playthings have neodymium magnets along their edges, letting you assemble them into a variety of shapes, including a dodecahedron. Each set comes with 12 pentagons, and the more kits you buy, the more complex the objects can get. They come in Slate, Cobalt, Aqua, and Lava.
The guys from Rotor Riot rigged up one of the cooler drone mods we’ve seen. By adding a set of four electromagnets beneath a quadrotor’s arms, they were able to land the flying machine sideways on metal surfaces, then release the magnets remotely to continue flying.
The opposing forces of magnets can produce a tremendous amount of energy, and can even be used to levitate and move trains along a track. In this clip from Magnetic Games, he demonstrates these physics at work, though on a smaller scale using a bunch off-the-shelf neodymium magnets he got from Supermagnete.
Magnetic Games loves to build complex sculptures out of magnetic spheres and rods. Not only are these fun to look at, but the sound they make when they click together is quite satisfying. It’s just as entertaining to watch them crumble, and the noises are equally ASMR, so put on your headphones and enjoy.
Magnetic Games presents yet another wonderfully satisfying video, in which he uses hundreds of magnetic rods and spheres to create an complicated geometric sculpture. He placed a light at the center of his masterpiece, so it casts interesting shadows as well. After it’s all done, he knocks it down with a catapult.
Magnet fanatic Magnetic Games got their hands on 64 oversize 26mm (~1.02″) neodymium spheres. These giant-sized balls are much harder to work with (and more dangerous) than their smaller brethren, but they do look like fun. They’re not cheap, but you can buy some here.
Silwy’s unique crystal glasses have magnets in their bottoms. They work with the included non-slip magnetic gel pad coasters to ensure that your drinks don’t spill on their way, and the available steel mounting strip let you hang them over or alongside your countertop. Glasses sold in sets of two.
Nintendo fans, dress up your fridge with your own custom level from Super Mario Bros. This set comes with 80 8-bit magnets from the Mushroom Kingdom, including bricks, pipes, gold coins, Koopas, Goombas, Mario, and Luigi. Just look out for those Piranha Plants.
Fishbone’s metal gadget is designed for knotless joining and tying of ropes and straps. It holds up to 0.5″ rope or 1″ flat webbing, and has built-in neodymium magnets for stacking and storage. Available in stainless steel or lightweight aluminum. They also make a mini version for paracord and skinny cord.
This customizable organizer system helps keep your desk free of clutter. Its consists of two different kinds of board and a set of pockets, clips, and holders, each of which attaches magnetically. It’s available as a angled desktop model as well as a portable folio, and you can easily rearrange and swap items between them.
If you’ve ever been working on a repair project and dropped a screw into a tight, dark space, you know what a pain that can be. This flexible metal tool has both a flashlight and a strong magnet on its tip, eliminating frustrations when you lose hardware into the abyss. It measures 24″ long and its magnet can lift 4 lb.
Designers Graham Plumb and Stephen Braitsch collaborated on this amazing mechanical display that uses a series of 180 magnets to write text in a pool of ferrofluid. They built 10 custom machines which are programmed to raise and lower magnets, creating the segmented letters in the oily fluid.
Electrical engineer Mehdi Sadaghdar of ElectroBOOM presents a series of simple demonstrations involving magnets, batteries, and wires, each of which might seem magical, but can all be easily explained by science. He might have a goofy approach to teaching, but if you stick around, you might learn a thing or two.
Despite their YouTube channel’s name, The Philadelphia Robot Factory has significantly more magnets than robots. In this highly satisfying video, they disassemble a hefty hexagonal structure they made from 50,000 individual magnetic spheres, layer by layer. Now enjoy the same in reverse.
Puzzle maker Ravensburger’s kits are a blast for kids and kids at heart, letting you easily assemble fast-moving and complex marble runs. Modular components encourage experimentation, and include loops, magnetic cannons, and other tricks. The starter set comes with 122 pieces, while we’d go for the 240-piece XXL set.
Full Windsor, maker of the Muncher multi-utensil, extends its lineup with these slimline aluminum eating tools. This literal flatware has embedded magnets and couplers for easy stacking in your drawer, backpack, or for grouping them together at the table. Carry them every day, and cut down on environmental waste.
Magnets and destruction. What’s not to like? Magnetic Games rigged up a variety of fragile panels in front of a powerful neodymium magnet, then launched a steel sphere in its direction, and captured the smashy goodness in slow motion. Don’t try this at home without proper eye and face protection.
Vat19 shows off some of the fun things you can do with these glow-in-the-dark magnetic construction spheres. Each pack comes with 216, 0.5 cm diameter neodymium balls, but if you pick up 24 packages or so, you can build yourself a magnetic lightsaber, just like they did.
Want to make sure your screws and bolts don’t slip when you’re driving them? Jakemy’s handy shop accessory can magnetize your steel tools like screwdrivers, drill bits, tweezers, and anything else that slides through its slots. It’s available in small and large sizes for various tools.
Magnets are extremely useful for welding steel, as they can be used to hold pieces securely together without clamps. Strong Hand Tools magnets are unique thanks to their double-jointed design, which allows them to hold round, flat, or square metal parts at any angle, and in a snap.
Magnet enthusiast Magnetic Games decided to see what would happen when he introduced a bunch of his small, Buckyballs-style spheres to some of his incredibly powerful neodymium monolith magnets. The impacts are quite spectacular, and especially neat to watch in slow motion.
Magnet fanatic Magnetic Games shows us how to build cube structures using neodymium metal rods and spheres. He starts out with a single cube, then builds on it to create a much more substantial cube. The sounds the magnets make as they snap into place are wonderfully satisfying too.
