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 ...

For over a century, scientists have known that electric currents bend in a magnetic field—a phenomenon known as the Hall effect. In magnetic materials like iron, this effect is strong and well ...

Why would you want to detect metal? Oh, I don't know … maybe you want to find some gold in the ground. You could dig up ALL the dirt, or you could find the location that has the gold before you dig.

Scientists have cracked a century-old physics mystery by detecting magnetic signals in non-magnetic metals using only light and a revamped laser technique. Previously undetectable, these faint ...

New method detects magnetic signals in metal that make it possible to predict fractures before they occur and prevent critical failures.

Superconductivity—the ability of a material to conduct electricity without any energy loss to heat—enables highly efficient, ...

Two recent innovative projects that are being enabled by lasers. How lasers make it possible to assess the very subtle magnetism of “non-magnetic” metals. The use of lasers to quantify ...
