How do magnets create a force? Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for ...

In a recent study published in the journal Science Robotics, a team of researchers created a magnetic microrobot probe that can quantify the stiffness and traction force of tumor cell colonies and ...

Today's computers store information using only two values: 0 and 1. But as electronic devices become smaller and reach their ...

Researchers at Chalmers University of Technology in Sweden published their findings in Advanced Materials, demonstrating a material that allows two competing magnetic forces to coexist within a single ...

Traditional magnetic separators, however, present a challenge: they generate a magnetic force that is very high near the side of the vessel closest to the magnet and decreases rapidly with distance.

Research teams led by Prof. Zeng Changgan and Zhang Hui from the Hefei National Laboratory for Physical Sciences at the Microscale, the University of Science and Technology of China (USTC) of the ...

A team of scientists has developed a powerful new way to detect subtle magnetic signals in common metals like copper, gold, and aluminum—using nothing more than light and a clever technique. Their ...

A strange, glowing form of matter called dusty plasma turns out to be incredibly sensitive to magnetic fields. Researchers found that even weak fields can change how tiny particles grow, simply by ...

Magnetism is usually taught as a story of straight lines, with field arrows marching neatly from north to south. In a lab at Florida State University, that picture has just been shattered by a new ...

Conventional soft actuators are often limited by weak force, small displacement, and slow response. To overcome these ...
