Superconductivity and Superconductors

ABSTRACT

Superconductivity allows current to pass through a

material with no resistive losses at near absolute zero

temperatures. It also exhibits the Meissner effect which

causes the superconducting material to repel magnetic

fields. The application of this technology has been

extremely limited due to the prohibitive costs of using

Helium to cool the material to the critical temperatures.

Recently, however, new ceramic materials were

discovered which exhibit superconductive properties at

higher temperatures which can be reached using cheaper

liquid Nitrogen cooling. Applications have immediately

expanded and are expected to become amazing in the near

future as scientists search for a room temperature

superconductor.

ORIGINS

Superconductivity is the passing of electricity through

conductors with no loss of power (Graham 17).

    Electric guitars are devices that generate sound from a set of pickups that convert string vibration into electrical signals for amplification. The sound starts out as vibrations the musician creates while playing. These vibrations are picked up by the pickups of the guitar. What are pickups? Pickups are permanent magnets wrapped around in a coil. Since the strings are made with a special material called ferromagnetic, they interact with the magnetic fields in the pickups and force electrons to move in the loop. Moving electrons can generate a signal that can be read by the amplifier.

  • The Magnetism of Polar Opposites

    1531 Words  | 4 Pages

    How can a man entangled in the dangerous crimes of smuggling, so engrossed with his past love that he lost her, and shed his own blood due to a misunderstanding ever be forgiven? In other words, should he be condoned for his acts, or should he forever be in Hell and forgotten? One might acknowledge the fact that this man's past, behavior, and intentions are unknown, therefore standing in either a positive or neutral view. Another might add that sins can never be forgiven, no matter what reasons had caused them, leaning toward a negative standpoint. Jay Gatsby, a character in F. Scott Fitzgerald’s novel The Great Gatsby, is much like the preceding man described, having faced the shame and committing the same dishonorable acts, and is often criticized by those in a negative standpoint. However, within the text, Nick Carraway, the narrator of the novel, plainly states, “Gatsby turned out all right at the end” (6). Nick knew all about the immoral deeds Gatsby had carried out, so how could Nick make this claim in honor of a dead man? The answer is quite simple: Nick realized Gatsby’s incorruptible dream was the most admirable feat out of all the characters in the book, something that not only made Gatsby respectable to Nick, but great.

  • Magnetism And Magnetism

    831 Words  | 2 Pages

    Magnetism is very useful in our daily life. A magnetic field is a mathematical description of the magnetic influence of electric currents and magnetic materials. In addition, magnetic field is a region which a magnetic material experiences a force as the result of the presence of a magnet or a current carrying conductor. Current carrying conductors also known as wire. As we know there have north pole and south pole of a magnet. If same pole of magnet approaches each other, there will repel each other. In contrast, if different pole of magnet approaches each other, they will attract. These are same with the electric charge, if same charge it will repel, different charge it will attract. Although magnets and magnetism were known much earlier, the study of magnetic fields began in 1269 when French scholar Petrus Peregrinus de Maricourt mapped out the magnetic field on the surface of a spherical magnet using iron needles [search from Wikipedia]. Noting that the resulting field lines crossed at two points he named those points 'poles' in analogy to Earth's poles. Each magnet has its own magnetic field which experiences a force as the result of the presence of a magnet and magnetic field has made up of magnetic field lines. The properties of magnetic field lines is it begin at the north pole and end at the south pole. The north pole always flow out while south pole always flow in. The closer the magnetic field lines, the strength of magnetic field increases. Furthermore, these line cannot cross each other. Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets. Ferromagnetic materials...

  • Sue Monk Kidd's The Secret Life of Bees: The Nature of Grief

    1715 Words  | 4 Pages

    Grief leaves an imprint on those who experience it. Some can survive its deep sorrow, others cannot. In The Secret Life of Bees, by Sue Monk Kidd, she explores the effect of grief on the main characters. The novel opens with fourteen-year-old Lily Owns struggling with the knowledge that her mother was dead because she, as an infant, picked up a loaded gun and accidentally shot her. She runs away from her abusive father in search for answers of who her mother was. Lily hitchhikes to Tiburon, South Carolina; the location written on the back of an image of the Black Madonna – one of the only belongings she has of her mother’s. There, she finds a pink house inhabited by the Boatwright sisters who are African American women making Black Madonna honey. The Boatwright sisters have had their share of grief with the death of two of their sisters and the racial intolerance they face despite the passage of the Civil Rights Act. The Boatwright sisters and Lily Owens have different methods of coping with grief; internalizing, ignoring, and forgetting are some of the ways they cope, with varying degrees of success. They discover that they must live past their grief, or else it will tear them apart.

    For the purpose of this assignment the experience of attending Electro-Convulsive Therapy will be discussed. It will include rationale for the procedure, an account of the procedure and the student nurses reflection on the experience using Gibbs’ model of reflection (Jasper 2003). Electroconvulsive therapy (ECT) is a medical treatment for severe mental illness in which a small, carefully controlled amount of electricity is introduced into the brain. This electrical stimulation, used in conjunction with anaesthesia and muscle relaxant medications, produces a mild generalised seizure or convulsion (Mankad et al 2010).

    Loss can leave us with the feeling that we are no longer in control of our lives, a strong feeling of instability. We must understand our loss to cope and deal with what has happened. Jo Ann Beard the narrator and author of “The Fourth State of Matter” struggles with several losses throughout the text. She appears to deal with her instability by caring for her aged dog as if she was a sick child, when in reality Beard just wants her problems to disappear. When faced with a complication a difficult choice must be made, to do nothing in hopes the problem will resolve itself or face it head-on. When pretending the problem doesn't exist or similarly telling yourself it will go back to how it was, simply allows

    The Ultimate Nature of Matter. The theory of quantum mechanics has divided the atom into a number of fundamental sub-atomic particles. Although the physicist has shown that the atom is not a solid indivisible object, he has not been able to find a particle which does possess those qualities. Talk of particles, though, is misleading because the word suggests a material object.

    Many of us enjoy watching crime scene investigation shows, but in the criminal justice system forensic investigation is an essential field that requires upright observations and a prodigious interpretation. Under forensics, it is difficult to blame someone without scientific data. For that reason, Larry K. Gaines author of the textbook Criminal Justice in Action explains the importance of Blood Spatter Analysis. Specialist can learn a great deal about violent crime by examining where blood landed at the scene, the size and consistency of drops, and the pattern of blood spatter (Gaines, 2011). Consequently, an article of the Blood Spatter Analysis will be used to explain the research methodology the author uses to proceed certain investigations.
