The average Hackaday reader likely knows, at least in the academic sense, what a magnetic field looks like. But as the gelatinous orbs in our skull can perceive only a tiny fraction of the EM ...

A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction ...

Tiny magnetic "flowers" engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These ...

Experience the mesmerizing magic of ferrofluid as it reacts to magnetic fields in a bottle ... Dive into the world of magnetic games and illusions, and enjoy the science behind this magnetic ...

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

One field matched the magnetic force of a site in the Gulf ... we now need to consider potential impacts of human activities on these different mechanisms,” Evans said.

Creatures from migratory eels and other fish species to insects to birds tap into the Earth’s magnetic field to navigate, sometimes many thousands of miles. But so far, evidence has been scant for any ...

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 ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...

Magnetic devices are components for creating, manipulating or detecting magnetic fields. This can include magnetic memories, magnetometers and devices for magneto-optics. Magnetism can also play a ...

How a tokamak works: The electric field induced by a transformer drives a current (big red arrows) through the plasma column. This generates a poloidal magnetic field that bends the plasma current ...

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, ...
