Signification de "magnet" dans le dictionnaire anglais

Un aimant est un matériau ou un objet qui produit un champ magnétique. Ce champ magnétique est invisible mais est responsable de la propriété la plus notable d'un aimant: une force qui tire sur d'autres matériaux ferromagnétiques, tels que le fer, et attire ou repousse d'autres aimants. Un aimant permanent est un objet fabriqué à partir d'un matériau qui est magnétisé et crée son propre champ magnétique persistant. Un exemple quotidien est un aimant réfrigérateur utilisé pour tenir des notes sur la porte d'un réfrigérateur. Les matériaux qui peuvent être magnétisés, qui sont aussi ceux qui sont fortement attirés par un aimant, s'appellent ferromagnétique. Ceux-ci incluent le fer, le nickel, le cobalt, certains alliages de métaux des terres rares et certains minéraux naturels comme le lodestone. Bien que les matériaux ferromagnétiques soient les seuls attirés par un aimant assez fort pour être généralement considérés comme magnétiques, toutes les autres substances répondent faiblement à un champ magnétique, par l'un des plusieurs autres types de magnétisme. Les matériaux ferromagnétiques peuvent être divisés en matériaux magnétiquement "doux" comme le fer recuit, qui peuvent être magnétisés, mais ne tendent pas à être magnétisés et à des matériaux magnétiquement "durs" qui le font. A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic. These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field, by one of several other types of magnetism. Ferromagnetic materials can be divided into magnetically "soft" materials like annealed iron, which can be magnetized but do not tend to stay magnetized, and magnetically "hard" materials, which do.

It's kind of a mysterious process, but something will catch my attention, and I'll make a note about it. I may even write a few pages about it, and then I'll put it aside, but I'll sort of keep it in mind. Then as time goes on, other things will gather to it as if it's a magnet, almost, and eventually, there's enough to make the story.

Just like the poles of a magnet, some people are drawn to death and others are repulsed by it, but we all have to deal with it.

I know how I felt when I saw things like 'Fame' on television when I was growing up and how that was an exceptional magnet for me to want to explore the theater. I can only assume that 'Smash' is doing that for anyone who is halfway interested in theater already.
