In the free resource for teachers, Mwaksy and Greg observe how magnets attract or repel each other and attract some materials ...

Within their planetary systems, stars are continuously shaping their orbiting planets through gravity, radiation and magnetic forces. So far, this relationship has appeared to be a one-way street.

What is Magnetic Force Microscopy (MFM)? Magnetic Force Microscopy (MFM) is a scanning probe microscopy technique that allows the imaging and characterization of magnetic properties of materials at ...

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 ...

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 ...

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 ...

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.
