A magnet's magnetic moment (also called magnetic dipole moment and usually denoted ) is a vector that characterizes the magnet's overall magnetic properties. For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole,  and the magnitude relates to how strong and how far apart these poles are.
Magnet wire or enameled wire is a copper or aluminium wire coated with a very thin layer of insulation.It is used in the construction of transformers, inductors, motors, speakers, hard disk head actuators, electromagnets, and other applications that require tight coils of insulated wire.. The wire itself is most often fully annealed, electrolytically refined copper.

Jul 16, 2018·Synchronous Machine is electromechanical equipment in which the speed of rotating part i.e., Rotor, is equal to the speed of rotation of magnetic flux. The speed of rotation of magnetic flux is called synchronous speed. That is why these types of equipment is called synchronous machine. This article outlines the constructional detail and type of
Copper gaskets are commonly used with ConFlat ® (CF) flanges. When copper gaskets are baked at 400°C, oxidation of the copper limits the number of bakeouts to 20 to 30. A dry film coating of molybdenum disulphide is helpful on bolts used with CF flanges to obtain the maximum clamping with minimum torque.

Like all of the electrical distribution equipment serving critical systems, transformers are a key component. That's why it's crucial to evaluate your decision from every angle before choosing a unit. To help you narrow the playing field, let's take a look at some of the most important factors to consider when specifying or purchasing primary dry type transformers, which typically feed a large
The prudent design of a dry disposal system, whether it be dry stacking, thickened tailings disposal or paste fill, requires prediction of the angle of repose, or slope formed by the deposited tailings. Prediction of the slope formed by the tailings allows the residue area to be sized to ensure maximum storage efficiency and stability.
Jan 01, 2002·On the other hand, it is known that many metallophthalocyanines possess magnetic behavior , , , , and it may be possible to control the orientation of molecular stacking of metallophthalocyanines using a magnetic field. This paper thus describes a way to grow copper phthalocyanine (CuPc) films by vacuum deposition under a magnetic field.
May 09, 2017·A VPI dry type transformer is the one which has primary and secondary winding impregnated with resin within a vacuum chamber. We can see the winding physically opening the door of the transformer. But a CRT dry type transformer has its primary and secondary winding moulded. The winding becomes a solid mass after this mould casting is done.

Surface stacking is the disposal of tailings on the surface of the ground. As a non settling, non segregating suspension of solids, minimal water is released into the impoundment and the stacked tailings dries significantly faster than conventional ponds where fines (slimes) segregate and can seal the surface of the deposit, preventing drying.
