the symbol I and called its nuclear spin. This spin is then determined by its quantum number, which is represented by the symbol S. Each nuclear spin is associated with a magnetic moment. When this moment is placed in an external magnetic field, these spin states differ in magnetic potential energy. If placed in a static magnetic field with a small amount of spin polarisation however, certain radio frequency signals can allow a transition between spin states, with some of the spins being placed…

Magnetic resonance imaging, also known as an MRI scan, is a type of scan that uses magnetic fields and radio wave energy to create images of the organs and tissues, such as the brain. It is a scan that is used to detect things such as tumors, infections and injuries. It is often used after an x-ray or CT scan is done to gather more information. This paper will discuss MRI in depth such as how an MRI works, its use in society, the differences between MRI and other scans and the future for MRI.…

Turbulence May Spawn Monster Magnetic Fields discusses a lab experiment that aimed to investigate the mysterious and powerful properties of magnetism in space. Magnetic waves are extremely prominent in our universe, which consists of dense galaxy clusters and vast voids of space separating these clusters. While it seems obvious magnetism would be present in the various galaxy clusters, as they are active regions of space, astronomers have also discovered a very strong magnetic presence in the…

Review of Stacking Interactions of Nucleobases: NMR Investigations by H. Sapper and W. Lohmann Introduction Nuclear magnetic resonance (NMR) spectroscopy is often a very useful tool to identify organic molecules based on the atomic nuclei interactions with their environment. Recent advances have made use of the technology in protein, nucleic acid, and complex natural products structure identification. [1, 2, 3] Its origins lie in the works of Felix Bloch and Edward Purcell, who used the…

alone. Geophysicists use Magnetics in order to locate the unexploded ordnance to prevent accidents and damage to infrastructure as these devices may still be active. This is done via a variety of ways and applications. By mainly using magnetic waves we are able to detect certain anomalies in data to a certain…

1.Magnetic resonance imaging uses the property of Nuclear Magnetic Resonance to take the image of nucleus has magnetization of its own and in MRI scanner patient is placed between a large magnet. This allows nucleus of atoms to align themselves according to their magnetization which leads to the production of magnetic field which is noticed by MRI scanner. This is how magnetic resonance imaging exploits the magnetics properties of the nucleus. 2. Sound waves are longitudinal waves and they…

makes the domains behave like a tiny little bar magnets just like the kind you have probably played with at school. The needle of a compass is also a bar magnet, and we know what this does: it points north because it likes to line itself up with the magnetic field of the earth. "However, if you bring the needle close to another…

MRI and the risks and benefits. Magnetic resonance imaging (MRI) is an examination that uses a magnetic field and three dimensional detailed anatomical images to take pictures of the inside of the body. In many cases, MRI gives different information about structures in the body that can be seen with an ultrasound, X-ray, or even a computed tomography scan or as we know it as CT scan. An MRI can also show problems that you cannot see from other image systems (Magnetic Resonance Imaging (MRI) 1).…

society, especially tattoos. One writer says, “Permanent tattooing is the process of body modification by deposition of a pigment into the dermis” (Simunovic and Shinohara 525). In the past three decades, magnetic resonance imaging (MRI) has become increasingly popular in the medical field. Magnetic resonance imaging is a type of medical imaging that is non-invasive and safe in most cases. However, in some cases, patients with tattoos who have undergone MRI scans have experienced first and…

Magnetic resonance imaging (MRI) is a non-invasive imaging tool that can provide increased contrast between soft tissues to visualize structure and function thereof for diagnostic purposes. MRI has high spatial and temporal resolution and is safer than other imaging modalities because it does not require ionizing radiation. Rather, MRI is based on the behavior, interaction, and alignment of water protons that are found in soft tissue when an external magnetic field is applied. The magnetic field…
