octacyanomolybdate(IV) anions‚ Mo(CN)84-‚ of approximate dodecahedral‚ D2d‚ and square antiprismatic‚ D4d‚ symmetry. The sensitivity of the Mo magnetic shielding (σ) and electric field gradient (EFG) tensors to small changes in the local structure of these anions allows the approximate D2d and D4d Mo(CN)84- anions to be readily distinguished. The use of high applied magnetic fields‚ 11.75‚ 17.63 and 21.1 T‚ amplifies the overall sensitivity of the NMR experiment and enables more accurate characterization

Magnetic Fields PHY 114 Lab Report 10/23/2013 Abstract: The purpose of this experiment was to surrounding a magnet there is a magnetic field. The magnetic field is analogous to the electric field that exists in the space around electric charges. Like the electric field‚ the magnetic field has both a magnitude and a direction. The direction of the magnetic field at any point in space is the direction indicated by the north pole of a small compass needle placed at that point. Since electric

Chapter 1 Electrical discharge machining (EDM) 1.1 Introduction: Electrical discharge machining (EDM) is one of the most extensively used non-conventional material removal processes. Its unique feature of using thermal energy to machine electrically conductive parts regardless of hardness has been its distinctive advantage in the manufacture of mould‚ die‚ automotive‚ aerospace and surgical components. In addition‚ EDM does not make direct contact between the electrode and the workpiece eliminating

generation the physical means such as gravity‚ vacuum or magnetic field is used for stabilization of the free flowing dry moulding materials. The development of unbounded casting process improves flexibility and enhances mould ability. The concept of unbounded casting is to change the kind of binder or to avoid substantial binder. Magnetic moulding is a type of unbounded moulding process in which a dry and free flowing magnetic steel shots or granules are used as mould materials

TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum

The Earth’s Magnetic Field This article will cover three large concepts about the Earth and its magnetic field. The first concept we will talk about is the fact the Magnetic North is NOT at the North Pole. This is because the magnetic North moves about a lot and does not always match up with the geographical north (the north pole). The diagram above shows us the difference between these two poles. The orange rectangle represents the giant ‘magnet’ inside the

Magnetic ink is very useful because it is readable both by humans and by specialized equipment. It is one of the components that makes it possible to process personal checks securely‚ quickly and accurately. Magnetic ink character recognition (MICR) is a character-recognition technology used mainly by the banking industry to ease the processing and clearance of cheques and other documents. The MICR encoding‚ called the MICR line‚ is at the bottom of cheques and other vouchers and typically includes

Magnetic particle inspection (MPI) - Is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferroelectric materials such as iron‚ nickel‚ cobalt‚ and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs
