With magnetic curtain rods, you don’t have to drill screws into your wall, so they are easy to both install and remove. Skip to content. FOX31 Denver.

An iron rod placed inside a coil carrying a current will become an induced magnet. If the current is dc, the ends of the iron will become a N-pole and a S-pole.

Wrought iron is an iron alloy with very low carbon content with respect to cast iron. It is soft, ductile, magnetic, and has high elasticity and tensile strength. It can be heated and reheated and ...

Magnet fisher James Kane cradles a shiny, four-pound magnetic disk: a stainless-steel shell housing an alloy of iron, neodymium and boron. He hucks it into a lake in a public park in New York City ...

Before this neodymium-iron-boron magnet came along in 1984, electric motors, generators, audio speakers, hard-disk drives, and the like had to make do with pricey samarium-cobalt magnets.

At pressures above 10 GPa, iron is known to transform to a non-magnetic structure1,2 and the possibility of superconductivity in this state has been predicted3,4.

To investigate Earth's magnetic field — which waxes, wanes and even flips over time — the researchers looked at grains of the mineral iron oxide in 32 clay bricks from ancient Mesopotamia ...

Their research supported evidence for the "Levantine Iron Age geomagnetic Anomaly," a time when the planet's magnetic field was surprisingly strong around what is now Iraq between 1050 and 550 B.C.
