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.
THE BEST Magnets
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.
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.
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.
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.
Silwy’s unique plastic cups and 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. Touch of Modern has some on sale as of this writing. Also on Amazon.
