Awesome Magnets

Making Hidden Locks with Magnets

Making Hidden Locks with Magnets

Sometimes, the best kind of lock is the kind that doesn’t look like a lock at all. B-Star Crafts shows off a simple, but effective method that keeps doors or drawers locked using hidden neodymium magnets. It’s a trick that’s frequently found in puzzle boxes but can be easily applied to furniture and cabinets as well.

Ferrofluid Venom Suit

Ferrofluid Venom Suit

The way that Venom comes to life from a pile of black ooze is awesomely creepy. JLaservideo wanted to replicate the effect in real life and figured out the best way to do it was to create a suit from 100,000 neodymium magnets and latex, then let ferrofluid do the rest of the work.

Making an Electromagnetic Launcher

Making an Electromagnetic Launcher

Electromagnets can be very powerful. They’ve even been used to get roller coasters and trains rolling and to launch fighter jets. Tom Stanton made a miniature system of homebrew linear synchronous motors which use electromagnetism to propel a small sled and launch various items including a hot dog and a paper airplane.

Ever been working on a repair or assembly project and dropped a screw into a spot where you can’t reach it? This unique tool is perfect for the recovery job, with its flexible telescoping head, a super-strong magnetic tip, and a built-in LED flashlight. Extends from 6.69″ to 21.65″.

How to Orient Nails

How to Orient Nails

Ever wonder how they get all the nails in a box to lay in the same direction? In this all-too-short and all-too-silent video clip, they show how a pile of randomly grabbed nails immediately point in the proper direction when dropped between a pair of electromagnets. Here’s another machine that does it without human intervention.

Levitating Motors

Levitating Motors

Magnetic fields can be pretty amazing. Given the right conditions, they can be turned into motors and even levitate. Magnetic Games shows off three different setups, each of which results in magnets floating and spinning with just a small boost of human or battery power.

STKR’s Magnetic Light Mines pack a dozen rare-earth magnets that allow you to easily position and aim their 15-lumen wide-angle LED in tight spaces. They also double as a pickup tool for screws and nails. The 3-pack is the best deal, dropping the price to less than $7 a piece. They also make a 250-lumen Light Mine Pro.

Magnetic Flywheel Generator

Magnetic Flywheel Generator

Aerospace engineer Tom Stanton has a thing for flywheels. Here, he first shows us how to build a flywheel that spins smoothly thanks to magnetic levitation, then how that spinning action can be used to generate a small amount of electricity and capture it via copper induction coils.

Making a Magnet Cuboctahedron

Making a Magnet Cuboctahedron

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.

Magnetic Gears

Magnetic Gears

Mechanical gears can change the speed or force by using different sizes and spacing of their teeth. But we had no idea that a similar result could be achieved by spinning discs embedded with different quantities and sizes of magnets. Magnetic Games shows off this surprising behavior in this neat physics demonstration.

Multi Diamagnetic Levitation

Multi Diamagnetic Levitation

With the help of the guys at the Magnet Tricks channel, Magnetic Games shows off a neat effect that occurs when placing tiny magnets between a block of pyrolytic graphite and a strong magnet aimed at them from at a distance. These mini magnets spin, dance, and shuffle about, and can even levitate off of the surface.

Longest Simple Electric Train

Longest Simple Electric Train

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.

Diesel Fish Rope Tie

Diesel Fish Rope Tie

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 0.25″ or smaller rope or paracord.

Ice and Magnets

Ice and Magnets

Magnet Tricks stepped out into the frigid cold of Finland to capture a series of compelling and unusual images created by freezing soap bubbles atop a magnetic levitation platform. Inspired by the idea, the guys at Magnetic Games then created their own version with a floating bubble inside another bubble.

How Magnets are Made

How Magnets are Made

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.

Speks Geode Magnetic Toys

Speks Geode Magnetic Toys

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.

Magnetic Sticky Drone

Magnetic Sticky Drone

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.

Magnetic Accelerators

Magnetic Accelerators

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.

ASMR Magnetic Demolition

ASMR Magnetic Demolition

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.

Giant Magnetic Balls

Giant Magnetic Balls

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.

Magnetic Letterpress

Magnetic Letterpress

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.

Spinning Magnets

Spinning Magnets

Magnetic Games presents another wildly satisfying video. This time, he uses a bunch of spherical and tubular magnets to create a series of gradually more complex spinning kinetic sculptures. It’s equal parts ASMR, physics experiment, and visual fun.
