A magnet assembly for a magnetron sputtering device having circular, linear or other types of planar targets including two permanent magnets and an electromagnet, e.g., electromagnetic coil between the permanent magnets associated with a sputtering target of a target assembly. An electrical control ...
Twitter Google Share on Facebook electromagnet (redirected fromElectromagnets) Thesaurus Medical Encyclopedia e·lec·tro·mag·net (ĭ-lĕk′trō-măg′nĭt) n. A magnet consisting essentially of a coil of insulated wire wrapped around a steel or iron core that is magnetized only when curre...
Electromagnets are useful because you can turn the magnet on and off by completing or interrupting the circuit, respectively. Before we go too much farther, we should discuss how electromagnets differ from your run-of-the-mill "permanent" magnets, like the ones holding your Popsicle art to the...
While permanent magnets are magnetic no matter what the situation is, an electromagnet requires current sent through them to show electrical and magnetic properties such as field and force. Permanent magnets have chemical and physical compositions of atoms, alloys and other materials that allow charge ...
17.The field may be provided by permanent magnets or by electromagnets. 外地可能提供的永磁材料,或由电磁铁. 18.An electromagnet behaves like a permanent magnet. Large electromagnets are used for lifting heavy iron object. 电磁铁能像磁铁般有吸力, 可用于搬勋重的铁. ...
Electromagnets differ from your run-of-the-mill "permanent" magnets, like the ones holding your Popsicle art to the fridge. As you might know, magnets have two poles: north and south. They attract things made of steel, iron or some combination thereof. Like poles repel and opposites attract...

the electric current applied; the stronger the current, the stronger the magnetic field produced. Electromagnets are distinct from hard magnets (manufactured or naturally occurring). The magnetic field of hard magnets is quite permanent or long lasting and is therefore not dependent on electric ...
Several tables and charts are presented which provide data on export and import market for electromagnets, permanent magnets, electromagnetic or permanent magnet chucks and clamps in Oceania in 2011 including one on the world exporters' market for these magnetic devices, another on target markets for...
