A samarium–cobalt (SmCo) magnet, a type of rare-earth magnet, is a strong permanent magnet made of two basic elements: samarium and cobalt.. They were developed in the early 1960s based on work done by Karl Strnat at Wright-Patterson Air Force Base and Alden Ray at the University of Dayton.
By choosing a magnetic material with a high (BH) max, and also choosing the aspect ratio of the magnet so that its −BH is equal to (BH) max, the required volume of magnet to achieve a target flux density in the air gap is minimized. This expression assumes that the permeability in the core that is connecting the magnetic material to the air ...
A magnet keeper is a specialised pole piece used to temporarily connect the poles of a permanent magnet, to help to preserve the magnetism, and for safety in the case of large and powerful magnets. Another specialised pole piece is the armature of an electromechanical solenoid , which produces work by being attracted by an electromagnet when ...
Magnetocrystalline anisotropy has a great influence on industrial uses of ferromagnetic materials. Materials with high magnetic anisotropy usually have high coercivity, that is, they are hard to demagnetize. These are called "hard" ferromagnetic materials and are used to make permanent magnets.
In that conversation, Butler reportedly told Riley that he won't sign an extension and will only use his $52 million player option for the 2025-26 season this summer as a way to help a trade along.
-Hackers have compromised several different companies' Chrome browser extensions in a series of intrusions dating back to mid-December, according to one of the victims and experts who have ...
The 29-year-old mother called 911 Thursday afternoon to report her 14-year-old son became unresponsive while she was spanking him with an extension cord, KOMO News reported.
Magnetostriction is a property of magnetic materials that causes them to change their shape or dimensions during the process of magnetization.The variation of materials' magnetization due to the applied magnetic field changes the magnetostrictive strain until reaching its saturation value, λ.
