Scientists have made promising steps in developing a new magnetic memory technology, which is far less susceptible to corruption by magnetic fields or thermal exposure than conventional memory. The ...

For nearly 20 years, physicists and engineers have chased the idea of invisibility. Early efforts focused on hiding objects from light using so-called metamaterials with extreme and often unrealistic ...

Low-frequency magnetic fields can impact electronic devices, inducing unwanted current flows in sensitive paths that can add noise, introduce errors, and otherwise disrupt carefully balanced circuits.

Researchers in Spain have proposed a new type of invisibility cloak that could hide objects from magnetic fields. The cloak – which has not been built yet – is designed to have a dual effect. It ...

Permalloy was primarily developed in the early 20th century for inductive compensation of telegraph cables. Permalloy is known for its very high magnetic permeability, which makes it useful as a ...

Scientists have figured out a way to create and cancel magnetic fields from afar. The method involves running electric current through a special arrangement of wires to create a magnetic field that ...

Magnetic illusion: a long wire surrounded by a magnetic replicator generates a replica of the wire outside it. (Courtesy: Phys. Rev. Lett. 10.1103/PhysRevLett.125.177204) Physicists in the UK and ...

Numerous test-and-measurement applications require a high-frequency magnetic field. Oftentimes, high field strength is needed. Examples of such applications include bio-medicine research on the effect ...

The origins of magnetic steel can be traced back to the 18 th century when scientists began experimenting with iron alloys. In 1820, Hans Christian Oersted's accidental discovery of electromagnetism ...
