What Does Diamagnetic Mean in Chemistry

There are different forms of magnetism, a list that includes ferromagnetism, antiferromagnetism, paramagnetism, and diamagnetism. Key Takeaways: Diamagnetism A diamagnetic substance does not have unpaired electrons and is not attracted to a magnetic field.All materials display diamagnetism, but to be diamagnetic, this must be the only contribution to its magnetic behavior.Examples of diamagnetic materials include water, wood, and ammonia. Diamagnetism In chemistry and physics, to be diamagnetic indicates that a substance contains no unpaired electrons  and is not attracted to a magnetic field. Diamagnetism is a quantum mechanical effect that is found in all materials, but for a substance to be termed diamagnetic it must be the only contribution to the matters magnetic effect. A diamagnetic material has a permeability less than that of a vacuum. If the substance is placed in a magnetic field, the direction of its induced magnetism will be opposite to that of iron (a ferromagnetic material), producing a repulsive force. In contrast, ferromagnetic and paramagnetic materials are attracted to magnetic fields. Sebald Justinus Brugmans first observed diamagnetism in 1778, noting antimony and bismuth were repelled by magnets. Michael Faraday coined the terms diamagnetic and diamagnetism to describe the property of repulsion in a magnetic field. Examples Diamagnetism is seen in water, wood, most organic molecules, copper, gold, bismuth, and superconductors. Most living organisms are essentially diamagnetic. NH3 is diamagnetic because all the electrons in NH3 are paired. Usually, diamagnetism is so weak it can only be detected by special instruments.  However, diamagnetism is strong enough in  superconductors  to be readily  apparent. The effect is used to make materials appear to levitate. Another demonstration of diamagnetism may be seen using water and a super magnet (such as a rare earth magnet). If a powerful magnet is covered with a layer of water that is thinner than the diameter of the magnet, the magnetic field repels the water. The minor dimple formed in the water may be viewed by reflection in the waters surface. Sources Jackson, Roland. John Tyndall and the Early History of Diamagnetism. Annals of Science.

Some of the more notable nurses are: Dorothea Dix- part of the founders of the US Sanitation Committee, Clara Burton-founder of American Red Cross, Louis May Alcott, and Helen Gilson. Clara Burton, also known as the â€Å"Angel of the Battlefield†, started out working in the federal government in the patent office. She was the first woman to ever hold senior clerkship, but once the war broke out, she gave up her job and went to help tend to the sick and wounded soldiers.

Lost in Yonkers and One Flew over the Cuckoo’s Nest Critical Lens Free Essays

The Unintentionally Hero Umberto Eco once wrote, â€Å"A real hero is always a hero by mistake†¦ † This quotation means that when a person doesn’t intentionally try to be a hero, but results in being the hero, is a true hero. I agree with this quotation, as it holds true in life and in literature. Both Lost In Yonkers by Neil Simon and One Flew Over the Cuckoo’s Nest by Ken Kesey, support that heros are those who act bravely upon themselves and not those who act the way to become the hero. We will write a custom essay sample on Lost in Yonkers and One Flew over the Cuckoo’s Nest Critical Lens or any similar topic only for you Order Now Lost In Yonkers is a story about a father, Eddie, who has to leave his two sons with his mother for care. He has to leave because he borrowed a mass amount of money from a loan shark to pay for his wife’s medical bills. Eddie tells his boys, â€Å"The doctors, the hospital, cost me everything I had†¦ And everything I didn’t have†¦ And finally it cost me everything i was going to have†¦ I was broke and I went into debt†¦ Into hock†¦ Only I didn’t have anything left to hock†¦ So i went to a man†¦ A shylock, they call him†¦ A loan shark. † A loan shark is a person who specializes in marking loads to desperate people. Eddie couldn’t have gone to the bank because the bank would of refused or asked for interest or for collateral, all of which Eddie can’t afford. A shylock doesn’t need collateral. His collateral is your desperation. When Eddie got the money form the Shylock, a clock starts. When the clock is up, the Shylock expects his money and if the money isn’t there, lives will be taken instead. The only way for him to pay back the Shylock was to take a job selling scrap iron; however, the job requires a lot of traveling. The only way for him to take the job was to leave his sons. It is revealed in the dialogue the misery he feels. He loves his sons tremendously and feels awful that he has to leave them for nine months. He says, â€Å"I’m not asking for myself. I’m asking for my boys. For my boys, I’ll be obligates,† to Jay and Arty. In this dialogue passage, he shows that for his boys, he’ll do anything. Eddie is being a true hero by stepping up to the plate and taking action for his early acts. He goes into deep debt by trying to save his wife, and now he has to risk his life to save his boys. He might not realize that he is a hero, but his actions justify the means. In One Flew Over the Cuckoo’s Nest, a man named Randle McMurphy becomes another victim in the mental ward under the control of Nurse Ratched, or also known as the Big Nurse by the other mental patients. Randle comes into the hospital ready to rebel and start a riot. At their daily group therapy session, Randle asks Nurse Ratched, â€Å"†¦ remember that vote we had a day or so back–about TV time? Well, today’s Friday and I thought I might just bring it up again, just to see if anybody else has picked up a little guts. † The vote was regarding about the patients and how they wanted to watch the World Series during TV time. The conflict is, Nurse Ratched doesn’t want the patients to have control. She likes to be in control. Once again, she wins the vote. At the climax of the first half of the book, Nurse Ratched lose her temper. Randle looks at the time and he realizes it’s time for the game. He â€Å"drags his armchair out to in front of the TV set, then switches on the set and sits down,† even though he lost the vote. The Big Nurse looks at Randle and then goes to the control room and flips a switch which causes the TV picture to swirl back into the gray. Even though this all happened, Randle is stilly sitting there. Nurse Ratched goes up to him and says, â€Å"I said, Mr. McMurphy, that you are supposed to be working during these hours,† in a tight voice. This is where she loses her temper. As she is warning Randle, other patients of the mental ward goes to grab a chair and pulls in next to Randle. Her last words were, â€Å"You men-Stop this. STOP! † before she was just like the rest of them, crazy. By hitting this climactical point, it shows that Randle McMurphy can really do anything he wishes. These two scenes where he stood up for what he wanted and what the other patients wanted showed that he is a hero. It may not be the genetically typically hero from some TV show, but a hero indeed. He fought for him and the other victims to be able to watch the World Series on TV but to be shut down by Nurse Ratched. Normally, no patient would even dare to suggest or question the Big Nurse. Randel stood up and stepped up. Also, when he dragged the chair in front of the TV, it showed he was not ready to be defeated so easily. He didn’t do these things to be a hero, but he did those things because he believe it was the right thing to do. What you see is what you get–we see Randle being a leader and brave and that is what we get. â€Å"A real hero is always a hero by mistake†¦ † means that people who unintentionally become the hero in the end are the true heros rather than those who try to become the heros with their actions. I agree much with this quotation for it holds true in life and literature. Eddie was a true hero in Lost In Yonkers and Randle was a true hero in One Flew Over the Cuckoo’s Nest.
