Explore how to calculate the magnetic force on a current-carrying loop from a long straight wire! This tutorial breaks down the physics concepts behind magnetic fields and forces, perfect for physics ...

Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use to ...

Light has always been described as an elegant partnership of electric and magnetic fields, yet for nearly two centuries ...

"As the magma cooled to form what is today the world's solid outer crust, magnetism was locked into minerals containing iron, such as magnetite." When you purchase through links on our site, we may ...

Traditional magnetic separators, however, present a challenge: they generate a magnetic force that is very high near the side of the vessel closest to the magnet and decreases rapidly with distance.

In MFM, a magnetic-coated AFM probe interacts with magnetic field gradients from the sample, causing detectable forces on the probe's cantilever. To focus on magnetic interactions, MFM is often ...

An international team of astronomers, led by SRON, has observed a sudden outburst of matter near the supermassive black hole ...

A technology that converts weak magnetic fields generated around power transmission lines into electricity has been developed by a domestic research ...

The Department of the Air Force successfully tested real-time magnetic navigation (MagNav) on a C-17 Globemaster III aircraft for the first time. MagNav uses a neural network and machine learning to ...
