Magnetic levitation — bismuth's ability to seemingly float between two magnets — is perhaps one ... "In paramagnets, when you ...

Bar magnets and horseshoe magnets are two of the most common shapes of magnet. The magnetic field is shown by lines with arrows that point from north to south. You can tell how old some coins are ...

Incidentally, [Dr.Stone] notes that the current version of the hardware and software can only handle one magnet at a time; visualizing complex magnetic fields and more than two poles would take an ...

When something draws us in like a magnet, we take a ... the application of an electric field. Their findings offer new ...

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 ...

the angle at which magnetic field lines intersect the Earth. The turtles use these two pieces of information, which vary at every point on the planet's surface, as navigational markers that help ...

Magnets are also surrounded by a similar three-dimensional field. This can be "seen" in two dimensions if iron ... The filings align themselves along the lines of magnetic force surrounding ...

The other magnetic field going around the length of the doughnut is referred to as toroidal (green horizontal circle). The combination of these two fields creates a three ... Twisting the magnets can ...

Iron particles effectively act as tiny magnets that can record both magnetic field strength and direction ... zircon crystals found in 3.4 to 4.2 billion-year-old rocks from Australia.

Magnetic field instruments are devices used to measure the magnetic field or flux around permanent magnets, coils, and electrical devices ... used to measure magnetic field strength. However, the two ...
