We present analytical formulations, based on a coulombian approach, of the magnetic field created by permanent-magnet rings. For axially magnetized magnets, we establish the expressions for the three ...

The magnetized rocks of Earth's crust and mantle, also known as the upper lithosphere, accounts for generating 6 percent of ...

Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether ...

For one, scientists observe a "cosmic fossil" called the cosmic microwave background (CMB). The first light that was free to ...

In an unexpected twist, Earth's spin is set to accelerate in July and August, leading to the shortest days on record - with ...

Magnetic materials are in high demand. They're essential to the energy storage innovations on which electrification depends ...

Although its accuracy problems have been shown many times in the literature, the magnetic-field integral equation (MFIE), either alone or in the context of the combined-field integral equation (CFIE), ...

PDF for physics from the official Punjab Board website. Access chapter-wise details for physics with the link to download the ...

In a world obsessed with the apocalyptic hellfire of ‘carbon’ and the terror of an imperceptibly warmer climate nowhere near ...

Exploring how animals use the Earth’s magnetic field highlights the remarkable intricacies of nature. From the epic journeys of migratory birds to the ocean-wide navigation of sea turtles and fish, ...

Geologic records reveal that magnetic field strength and oxygen levels rise and fall together, implying deep-Earth processes influence surface habitability.

Using compact magnets and 3D-printed rings, scientists have unlocked stronger, more even magnetic fields that could revolutionize MRI and magnetic levitation. Credit: Shutterstock Two German ...
