A new material developed at Penn State defies a fundamental law of physics, opening doors to highly efficient solar cells.
Magnetic Field around a current carrying wire Oersted’s law states that an electric current induces a magnetic field. It was observed that current-carrying wires created a circular magnetic field ...
The easiest way to remember the direction of motion in an electric generator is using Fleming’s right-hand rule. A different hand needs to be used for generators because of the differences between ...
A controversial rule passed by the Georgia State Election Board on Friday will require all of the state's voting precincts to hand-count ballots and ensure the tallies match machine counts before ...
The magnetic field around a straight wire is circular and follows the right-hand rule. When an electric current flows through the wire, it generates a magnetic field concentrically surrounding the ...
Amid the roilings of the Milky Way, immense pockets of gas coalesce into clouds where stars are born. In this process, there is a hidden hand at play: magnetism. “There’s this fantastic quote: You can ...
But exactly how that magnetic field is generated inside the sun is a puzzle that has vexed astronomers for centuries, going back to the time of Italian astronomer Galileo, who made the first ...
The Earth’s magnetic field protects us, and our orbiting tech, from the worst effects of the Sun’s energetic rays. But our magnetic field has a dent in it.
That’s the most powerful magnetic field ever detected in the universe by a huge margin – the previous record-holder was another pulsar with 1 billion Tesla, reported by the same team in 2020.
Magnetic field sources are dipolar, meaning they have a north and south pole. And when it comes to magnets, opposite poles (N and S) attract while other poles (N and N, S and S) repel.
