If you have a magnet, try seeing what objects it will attract or repel. Iron fillings reveal a magnet's magnetic field. You can see a magnet's magnetic field by scattering tiny iron filings around it.

This can be "seen" in two dimensions if iron filings are sprinkled on a sheet of paper placed over the magnet. The filings align themselves along the lines of magnetic force surrounding the magnet.

Many people will remember experiments in school with iron filings and bar magnets to unveil their magnetic field. It's not quite so easy to capture the magnetic field of the Milky Way though.

This allowed the team to detect and measure the unseen magnetic field lines, much the same way iron filings can reveal the magnetic field around a magnet. The team thinks that the measured three ...

Researchers have demonstrated that phosphorene nanoribbons (PNRs) exhibit both magnetic and semiconducting properties at room temperature. The research establishes PNRs as a unique class of ...

Room-temperature magnetic and electronic traits make phosphorene nanoribbons promising for next-gen, energy-efficient nanoelectronics.

The study "Magnetically and optically active edges in phosphorene nanoribbons" is available at: https://www.nature.com/articles/s41586-024-08563-x ...

In this study, the team analyzed biological systems from a magnetic perspective. They discovered that factors like abnormal iron metabolism, imbalances in antioxidants, and changes in free radical ...

Have you ever played with a magnet and stuck it in a sandy wash? It will pick up lots of black stuff. Some call it black sand; some might think ...
