A magnet's magnetic moment (also called magnetic dipole moment and usually denoted μ) is a vector that characterizes the magnet's overall magnetic properties. For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole, [ 15 ] and the magnitude relates to how strong and how far apart these poles ...
'Magnet' is derived from the legend of Magnes, or from the territory of Magnesia. Pliny states that Magnes, the shepherd, discovered it, and the legend told of him is that while carrying a message over Mount Ida he felt his feet clinging to the earth, to the iron ore which lay thickly upon the hill. Hence the name of the Magnet.
Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism.
Technologically, this is one of the most important processes in magnetism that is linked to the magnetic data storage process such as used in modern hard disk drives. [5] As it is known today, there are only a few possible ways to reverse the magnetization of a metallic magnet: an applied magnetic field [5]
Magnetic Poetry is a toy and creative writing aid consisting of individual words—often related to a particular theme or topic—printed on small magnets which can be creatively arranged into poetry on a refrigerator or other metal surface. [1] The informality and spontaneity Magnetic Poetry has endeared it to educators in creative writing. [2]
In the U.K., at least three children have been hospitalized after swallowing magnets for the TikTok trend. Faye Elizabeth's 13-year-old daughter swallowed 15 magnetic beads and required major ...
Magnets exert forces and torques on each other through the interaction of their magnetic fields.The forces of attraction and repulsion are a result of these interactions. The magnetic field of each magnet is due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the mater
“Developmentally, kids under 10, they’re going to be curious, they’re going to be reaching things. They don’t necessarily have the learned skill of ‘Hey, that might be dangerous. That ...
