Inventor Masato Sagawa demonstrating a NdFeB magnet's force with 2 kg bottle. A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure. [1] They are the most widely used type of rare-earth magnet.
Neodymium is the fourth member of the lanthanide series. In the periodic table, it appears between the lanthanides praseodymium to its left and the radioactive element promethium to its right, and above the actinide uranium. Its 60 electrons are arranged in the configuration [Xe]4f 4 6s 2, of which the six 4f and 6s electrons are valence.
e. Heavy metals are metallic elements with relatively high densities, atomic weights, or atomic numbers. The criteria used, and whether metalloids are included, vary depending on the author and context and has been argued should not be used. [2][3] A heavy metal may be defined on the basis of density, atomic number or chemical behaviour.
A permanent magnet motor is a type of electric motor that uses permanent magnets for the field excitation and a wound armature. The permanent magnets can either be stationary or rotating; interior or exterior to the armature for a radial flux machine or layered with the armature for an axial flux topology. The schematic shows a permanent magnet ...
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, steel, nickel, cobalt, etc. and attracts or repels other magnets. A permanent magnet is an object made from a material ...
The name "Kaisar-i-Hind" (Urdu: قیصرِ ہند qaisar-e-hind, Hindi: क़ैसर-इ-हिन्द) literally means "Emperor of India" in the Hindustani language. The word kaisar , meaning "emperor" is a derivative of the Roman imperial title Caesar , via Persian (see Qaysar-i Rum ) from Greek Καίσαρ Kaísar , and is cognate with ...
Jai Hind.
