‘Making’ magnetic sculptures

How are these magnetic sculptures magically clicking into shape from undefined piles? This Magnetic Games video in reverse turns the destruction of these intricate-looking sphere, cube, and rod magnet sculptures into ...

The Meissner Effect: How to levitate a neodymium magnet

A neodymium magnet cube sits on a surface of yttrium barium copper oxide—YBa2Cu3O7, nicknamed YBCO—inside the bottom of a styrofoam cup. A small amount of liquid nitrogen is poured slowly over the YBCO. As it cools, t...

These tiny origami robot transformers use magnetic fields to walk, roll, sail, and glide

This small cube can transform into a walking, wheeling, boating, or gliding bot with the help of origami exoskeletons that fold around it to create a new form and function. These are tiny shape-shifting robots from re...

Neodymium magnet collisions filmed in slow motion

What happens when Speks-style magnet balls, magnetic cubes, and plastic-covered disc magnets collide with large and powerful neodymium magnets? Watch them fly through the air, crash, and stick together in this slow-mo...

Smashing stuff with neodymium magnets

What happens to a cluster of grapes when it's in between two large, very strong and potentially dangerous neodymium magnets as they collide? Science presenter Kevin Delaney and his team demonstrate the power of these ...

The surprising interactions between copper and neodymium magnets

Experiments with super strong neodymium magnets and copper! These surprising demonstrations of magnetic damping go beyond the magnet through a copper tube demo that we've previously seen. Watch as Night Hawk in Light ...

Levitating pumpkins! Halloween superconductor science

What happens when you put a cooled superconductor, in this case, a YBa2Cu3O7 ceramic disk, into a tiny pumpkin and then place them both onto some neodymium magnets? Levitating pumpkin! In this Ri Channel video, su...

DIY Ferrocell: How to make a magnetic field viewer

By squishing a mix of mineral oil and ferrofluid between two sheets of glass, diligently squeezing out the air bubbles, sealing the edges, and then lighting it with a LED strip, Magnetic Games has created a DIY magnet...

What can you do with a large neodymium magnet?

Neodymium magnets are really strong. The larger they get, the more careful you need to be to avoid being pinched or struck from the force of their attraction. This video from Magnetic Games cautiously explores what ca...

How to make simple homopolar motor ‘race cars’

Lay out a 'race track' of tinfoil, attach two round neodymium magnets to the ends of an AA battery x2 (or more) -- the polarity of the magnets matters, so experiment to see how your vehicle behaves (or doesn't) -- the...

This mini origami robot self-folds, performs tasks, & can be dissolved

Researchers from MIT and TU Munich have debuted an insect-like, miniature, self-assembling origami robot at ICRA 2015. The tiny bot is 1.7cm by 1.7cm and is made of a neodymium magnet, PVC, and polystyrene or paper. W...

Dropping a neodymium magnet through a thick copper pipe

There are quite a few neodymium magnets falling through copper pipes on the internet, but we can still understand why this demonstration video is making the rounds: it’s just so cool lo...

Neodymium magnet + copper pipe = magnetic damping

Neodymium magnet + copper pipe = magnetic damping: When a magnetic field moves through a conductor a current called an Eddy current is induced in the conductor due to the magnetic field’s movement. The flo...


 
Not finding what you're looking for? A few suggestions:
• Fewer words might give better results. Look up cats instead of funny cats.
• No need to search with the words videos or for kids included.
• Use related words: If searching for iceberg isn't working, try ice or glacier.
• Is everything spelled correctly?
• Browsing topics might help, too!
