25-2 Magnetic field 物理学是整个自然科学和现代工程技术的基础。英文版大学物理课程的开设,首先是使学生掌握专业所必须的物理基础知识和专业词汇;进而要让学生对物理学的内容和方法、工作语言、概念和物理图像,其历史、现状和前沿等方面,从整体上有个全面的了解。这是
Magnetic field, a vector field in the neighborhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to lin
Wash—The beads respond to a magnetic field, allowing bound material to be rapidly and efficiently separated from the rest of the sample. Unbound material is simply removed by aspiration, and the bead-bound target is washed using a magnet/magnetic rack. ...
Magnetic field sensors are devices that detect and measure magnetic fields around permanent magnets, current conductors, and electrical devices. ADI MagIC+ is blurring the lines of what we previously

Magnetic field sensors are devices that detect and measure magnetic fields around permanent magnets, current conductors, and electrical devices. As the world becomes increasingly electrified, demand for improved positional and current sensing has grown in turn. ADI MagIC+™ breakthrough multiturn sensin...
Diamagnetism, kind of magnetism characteristic of materials that line up at right angles to a nonuniform magnetic field and that partly expel from their interior the magnetic field in which they are placed. First observed by S.J. Brugmans (1778) in bismu
Themagnetic fieldis an important thermodynamic parameter that has become available not only in laboratories but also in industrial applications through the development of superconducting magnets[1]. As an effective parameter, the magnetic field is extremely helpful in achieving microstructure modification and...
Static magnetic field (SMF) promoting bone tissue remodeling is a potential non-invasive therapy technique to accelerate orthodontic tooth movement (OTM). The periodontal ligament stem cells (PDLSCs), which are mechanosensitive cells, are essential for f
When the field sweeping direction is flipped, the direction of magnetization reverses again. Such linear domain walls and magnetic domain pattern evolution are consistent with the results of MFM, and has also been observed in other 2D magnets such as CrI3 and Cr2Ge2Te66,7. Our findings high...
