Research Question and Engineering Goal: Can an electromagnetic field melt metal screw nuts (zinc, brass, and stainless steel)? Our engineering goal is to create a device that will form an electromagnetic field that has the ability to melt an assortment of metals. It might look like magic; however, it is just science!
Background: Electromagnetic Field: (noun) a field that is made up of associated electric and magnetic components that result from the motion of an electric charge. It also possesses a definite amount of electromagnetic energy. Electromagnetic fields, or EMFs, is sometimes referred to as radiation. We are exposed to EMFs almost all the time. Almost all of the electronics or powered devices have some sort of electromagnetism in them. This includes your cell phone, kitchen appliances, television, lights, and computer. Electric door bells also use electromagnetic fields. When the button is pushed it signals for the coil to get electrified, then the bell sounds all because of the electromagnetic force. Perhaps the most well known application in society is Japan’s magnetically levitating bullet train. It’s capable of going up to 500 km/h without even touching the tracks. They have used the idea of electromagnetism to make magnets instead of wheels that have the ability to propel the train along with the help of electricity. This train is the fastest of it’s kind so far, but the idea is sure to spread because of the possibilities (which seem
Electromagnetic waves are continually used to upgrade and advance our technology, being implicated for its use in microwave ovens, radio waves for telecommunications and x-rays in medicine.
Several are working upon the use of electromagnetic pulses, specifically the electromagnetic gun (EM gun, rail gun, coil gun) as a way for new weaponry and advances in science.
The military has many uses for electromagnetic waves. They use it in the kitchen all the way to the battlefields. They use radio waves for seeing the damage that space dust could make. They use microwave radiation for cooking. They use Infrared waves for looking for enemies. They also use visible light to send streams of data. Two more waves are X-Rays and gamma rays. X-Rays are used for looking through other objects. Gamma rays are used for explosives.
I have always been coming up with crazy ideas on to build stuff. Most people would just look at me and shake their head. This project is based on one of those more crazy ideas. Most people don’t understand the awesome capabilities of magnets. This paper will discuss the research of magnets and the hopefully I will be able people the awesome things magnets can do.
Radiation is energy emitted from a source. It has the property to ionise when it has such a high energy, that at the moment it interacts with an atom, it can remove tightly bound electrons from its orbit, causing the atom to become charged (ionized).
Magnetism is the physics phenomenon produced by the movement of an electric charge causing in an attraction and repulsion force between an object. A magnetic field can be created by an electronic solenoid and can be influenced by multiple variables. The number of coils on a solenoid will affect the strength of the magnetic field. Furthermore, the length of the solenoid will determine the strength of the magnetic field. As more current is passed through a solenoid the magnetic field will greaten. Current and voltage are propionate and as voltage increases, so will the current. Many variables may affect the strength of a solenoid, some of which are the number of turns wrapped and length of the rod.
EM Waves are used all over the world and help the human life easier to live. They have helped discover and make things way easier. Electromagnetic waves are used all over the place everyone uses them. For example your camera uses Electromagnetic waves to get the picture that simple. Mankind could not live without EM waves because it would be hard to come up with devices that don’t use EM waves. Electromagnetic waves were found and made a huge impact to mankind.
There are various types of magnetic fields. Static fields are around permanent magnets. Quasi-static is the Earth’s magnetic field, which can vary a little. Radiofrequency magnetic fields can change in frequency and intensity. Low-level fields can regulate in producing reactive oxygen molecules that are known to influence cellular extent and survival.
An electro magnet is a type of magnet in which a magnetic field is created by a current, in our case of the
However there had done others study that express the connection between cell phones and different types of biological damage to human body. For example The European Journal of Scientific Research conducted a lab experiment with normal human astrocytes, an LG Verizon cell phone and MRET-Nylon chip. The experiment revealed that normal human astrocytes cell that were exposed to cell phone radiation at a room temperature without the MRET-Nylon chip decreased by 20% less . Igor Smirnov is one of the author of this experiment and he stated on his article that "It is well documented that cell phones, which emit electromagnetic fields in the radio frequency range, can cause DNA damage, headaches, blurred vision, dizziness,fatigue, short term memory loss, neuralgias, tumors, sleep disturbances, aberrant brain wave activity and changes to cerebral blood flow, including altering the permeability of the blood brain barrier" (Smirnov, 2009). Smirnov statement and finding about the emission of electromagnetic wave from cell phones gives a lot to think. Even-tough it's a small amount of radiation that is being emitted from cell-phones, because they are held very close to the head at the end of a long term usage the risk of brain cancer and others health problems will
The primary compound steel contained chromium and was protected in 1865 by American metallurgist Julius Baur and produced by the Chrome Steel Co. of Brooklyn, N.Y. This amalgam steel was never fruitful, yet the reputation provoked an enthusiasm for chromium combination steels by French metallurgist Henri-Ami Brustlein. He soon discovered that to composite chromium with steel, the chromium mineral should have been refined to create an expert amalgam of iron-chromium-carbon. This expert amalgam would promptly break up into the melt of the pot process, generally the recuperation of chromium would be excessively whimsical, making it impossible to control the compound substance. Brustlein created and sold chromium amalgam steels for instruments, gun shells, and covering plate over a time of around 15 to 20 years before any other person entered the field. For his work in creating combination steel and related warmth medicines and applications, Brustlein should be known as the Father of Alloy Steels.
Electromagnetic radiation is a form of energy that is all around us it takes up multiple forms. The forms are radio
An electricity and magnetism phenomenon apparently unrelated to power are electrical magnetic fields. We are familiar with these forces through the interaction of compasses with the earth's magnetic field, or through fridge magnets or magnets on children's toys. Magnetic forces are explained in terms very similar to those used for electric forces:
Multiple scientist developed theories about electromagnetism. One of the most popular ones is the Maxwell Equations. The Maxwell equations are equations explaining electromagnetism and how it works. These equations were formed by different equations and experiments. According to (Gale, 2001, WWW)Albert Einstein James Clerk Maxwell “”set the platform for physics and future scientists.” Maxwell’s theories were opposite from what other people thought. Maxwell´s theories also didn't have a lot of mistakes but there were quite a few mistakes in the velocity area. Maxwell’s theories brought a big change to electromagnetism. His theory connected and brought electricity and magnetism together.
1941, while working for the Raytheon Company, Percy Spencer discovered a more efficient way to manufacture magnetrons. This discovery led to significant advances in radar sonar, navigation, communication and undoubtedly his most popular invention, the microwave oven. Experiments showed that microwave heating could raise the internal temperature of many foods far more rapidly than a conventional oven.
