This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are ...

If you need help visualizing magnetic fields, these slow-motion video captures ... for a person used to a bar magnet. We should advise you before you watch the video below the break, if you ...

Because Earth's magnetic field is slightly asymmetrical and more complex than that of a regular bar magnet, the magnetic south pole — the point in the Southern Hemisphere where the magnetic ...

(Our planet's magnetic field should look a lot like the field around a bar magnet, but electrically charged particles in the solar wind push against the magnetic field, so the side pointing away ...

How a Generator Works When an electric current flows through a wire, it generates a three-dimensional magnetic force field around the wire, similar to that surrounding a bar magnet. Magnets are ...

Scientists know well how conventional materials conduct heat. However, things are not as straightforward under extreme ...

Would a dramatic change in the Earth's magnetic field affect creatures that rely on it during migration? Late on a January night in 1993 I found myself on a beach on the Pacific coast of Costa ...

A material’s response to an applied magnetic field can be characterized as diamagnetic, paramagnetic, ferromagnetic or antiferromagnetic. Four-coordinate cobalt(II) complexes possess high energy ...

The ability to conduct heat is one of the most fundamental properties of matter, crucial for engineering applications. Scientists know well how conventional materials, such as metals and insulators, ...
