Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel ...

If you need help visualizing magnetic fields, these slow-motion video captures should educate or captivate you. Flux lines are difficult to describe in words, because magnet shape and strength ...

A hot metal detector (HMD) can detect metals with temperatures that exceed the cure point. Non-ferrous metal detectors can detect aluminum, brass, and lead. Non-magnetic metal detectors are used to ...

Commissions do not affect our editors' opinions or evaluations. There’s something satisfying about the heft and feel of a metal credit card. Whether it’s the cachet that comes with owning one ...

The ability to control the magnetic properties of rare-earth metals opens new avenues related to their use. For instance, ...

And while we’re pretty sure that [Retsetman] didn’t invent it after hitting his head on the toilet, this magnetic gearbox is still really cool. Where most gearboxes have, you know, gears ...

In traditional understanding, electric polarization and magnetic order in materials were seen as mutually exclusive. However, ...

The data bits are recorded as magnetic spots on the tracks in one orientation or the other (0 or 1), and the smaller the bit, the greater the storage. See areal density and perpendicular recording.
