A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

A wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new ...

When an electrical conductor, like graphite, passes through a powerful magnetic field, it experiences energy loss due to ... these systems to unlock the full potential of this technology." ...

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

As with all currents, the induced current creates a magnetic field around itself. Note that this magnetic field opposes the original change. For example, if a magnet is moved into a coil of wire ...

Slip rings maintain constant contact with the same sides of the coil As one side of the coil moves up through the magnetic field, a potential difference is induced (created) in one direction.

Researchers have invented an entirely new field of microscopy -- nuclear ... of practical applications are possible The potential applications of magnetic resonance microscopy are up-and-coming ...

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, ...
