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

Where does the force come from? Electric currents and magnetic fields are closely related. If you have one, you often have (or can make) the other. The braking force in the demonstration is due to ...

Experience the mesmerizing magic of ferrofluid as it reacts to magnetic fields in a bottle! This captivating demonstration lets you observe the fluid’s behavior, creating stunning illusions and ...

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 ...

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.

Scientists have confirmed a 19-year-old theory on solar flare formation by observing “slip-running” reconnections in the ...

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 ...

but locked in place using a rotating magnetic field. The video shows a demonstration of how the mass of a magnet can be used to phase lock it against a rotating field. In essence, the magnet will ...

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 ...

In a fusion of science and art, Florida State University (FSU), the City of Tallahassee, and the National High Magnetic Field Laboratory ... 100 hands-on science activities.
