BH) max can be graphically defined as the area of the largest rectangle that can drawn in the second quadrant of the B-H loop. The maximum energy product is defined based on the magnetic hysteresis saturation loop ( B - H curve), in the demagnetizing portion where the B and H fields are in opposition.
Note: All measurements given are in picometers (pm). For more recent data on covalent radii see Covalent radius.Just as atomic units are given in terms of the atomic mass unit (approximately the proton mass), the physically appropriate unit of length here is the Bohr radius, which is the radius of a hydrogen atom.
For the first time in two decades, the Food and Drug Administration (FDA) has approved a new class of medication that provides an alternative to addictive opioids for patients looking to manage ...

The energy products of these samarium–cobalt alloys range from 16 MG·Oe to 25 MG·Oe, that is, approx. 128–200 kJ/m 3. These samarium–cobalt magnets generally have a reversible temperature coefficient of -0.05%/°C. Saturation magnetization can be achieved with a moderate magnetizing field.
264 Bh, 265 Bh, 266 Bh, and 271 Bh are more stable at around 1 s, and 267 Bh and 272 Bh have half-lives of about 10 s. The heaviest isotopes are the most stable, with 270 Bh and 274 Bh having measured half-lives of about 2.4 min and 40 s respectively, and the even heavier unconfirmed isotope 278 Bh appearing to have an even longer half-life of ...
The Vitória-Minas Railway (Portuguese: Estrada de Ferro Vitória a Minas — EFVM) [2] [3] is a Brazilian railway that connects the Metropolitan Region of Vitória, in Espírito Santo, to Belo Horizonte, capital of the state of Minas Gerais – a stretch of the EF-262 [].
