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 ...

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.

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 ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

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 ...

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 ...

Inductors are deceptively simple. However, a closer look reveals underlying complexity. How else can you explain the many types of core materials, types of windings, sizes, geometries and wide range ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...
