New results published in the journal Physical Review Letters detail how a specially designed metamaterial was able to tip the ...
The research team has identified atacamite as a material with magnetocaloric properties. Natural crystals have long ...
Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
Even when no food was to be had, turtles in the magnetic field they associated with food still showed “significantly higher levels of turtle dance behavior” than in the no-food field, and ...
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 ...
Worked Example A proton enters a magnetic field (B = 4 × 10 − 3 T) at the speed of 2.5 × 10 6 m / s. Determine the magnitude and direction of the force on the proton as it enters the field. To work ...
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 ...
Magnetic fields are everywhere in the universe. Of course, there's Earth's magnetic field, which deflects dangerous cosmic radiation, wiggles our compasses, and guides flocks of migrating birds.
The maximum field tolerance of these MRAM devices is between a few tens of milliTesla, mT, to 100mT, depending upon the MRAM target application. 10mT in SI units is 100G in CGS units of magnetic ...
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 ...
