Magnetic force microscopy (MFM) is a scanning probe technique that maps the magnetic properties of surfaces with nanometre-scale spatial resolution by detecting forces between a sample’s stray ...

Measuring faint magnetic fields is useful in a number of areas, including mapping brain activity, monitoring hearts and ...

Astronomers have achieved a major breakthrough in solar physics by successfully producing detailed maps of the Sun's coronal magnetic fields. This milestone promises to enhance our understanding of ...

A team of physicists and engineers at the University of Colorado Boulder has discovered a new way to measure the orientation of magnetic fields using what may be the tiniest compasses around—atoms.

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 ...

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 ...
