There's a dizzying variety of these 'neodynium magnet' 'desktoys/puzzles'. Most of them are sold as 6 * 6 * 6 (216) clumps, but you can get larger conglomerations of magnets for various prices. Of ...

Counterfeiters who sell knockoffs of popular shoes, handbags and other items are becoming increasingly sophisticated, forcing manufacturers to find new technologies to stay one step ahead. Now, ...

A team of Georgia Tech and Ohio State University researchers has developed a soft polymer material, called magnetic shape memory polymer, that uses magnetic fields to transform into a variety of ...

When you want to move an object from one place to another, you usually grab it with your hands or a robotic arm. But what if you want to move something you cannot touch without damaging or disrupting ...

The magnetic shape memory effect can be used for designing actuators where the element elongates based on the presence of a magnetic field. The elongation can be reversed fully either by the ...

Mag Cube -- a children's toy which uses dozens of tiny magnetic balls -- has been recalled because it could cause internal injuries if the balls are swallowed and then link together inside the body.

Small shapes 3-D printed with a special magnetic ink can be remotely controlled with the wave of a magnet and made to move, carry objects and even catch a ball. Stuart McDill reports. 27,637 people ...

Reporter Ellie Mackay looks into how researchers developed 1 a printable magnetic material that can be programmed to jump, contract and catch a moving ball. Read the research.

How could you build an artificial tadpole? Or simulate the motion of a cilium? Those would be hard to do with mechanical means — even micromechanical because of their fluid motion. Researchers have ...
