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 ...

Magnets are found all over the place. They hold items on the refrigerator while also holding the door shut. Our banking cards have magnetic strips — as do speakers, motors, and automatic doors.

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.

Scientists have observed atomic magnetic fields, the origin of magnetic forces, for the first time using an innovative Magnetic-field-free Atomic-Resolution STEM they developed. The joint development ...

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 ...

Magnetic forces, like the problematic but not, radioactive energy of cell phones, diminishes with distance. The researchers set out to determine how far the magnetic field of those two Apple devices ...

A Swedish-German-Luxembourg-Chinese collaboration demonstrated the existence of these magnetic hopfions using femtosecond ...

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 ...
