2. On the ends of the variable gap magnet there were two small magnetic disks. One arm of the magnet was unscrewed and removed from its housing. A meter stick was placed on the and the arm was on its side parallel to the meter stick. The Gauss-Tesla meter was used to measure the field strength of the magnet. The probe attached to the meter was perpendicular to the meter stick. There were 4 steps to this process:…
P7 describe the properties and an application of two different magnetic materials commonly used in electrical and electronic engineering.…
Semiconductors allow the flow of both ions and electrons through the sample but not completely free; and its conductivity increases with increasing temperature. Superconductors are a class of metallic conductor whose resistance drops to zero suddenly below a certain critical temperature.…
12. Then, as a kind of an afterthought, he added, "Do you suppose Hey Bag and I can get a job with the circus when I grow up?" 1. In 1831, a man named Michael Faraday, my history teacher, began experimenting with a magnet and a copper disk.…
There are several benefits that we can gain from the development of MRI imagining technology. A common argument for continuing the research in atomic and sub atomic structure is basically due to the greater understanding of the universe. Specifically, we gain better understanding of how the structure of the atom works, as we study the interaction of small particles which gives us a better understanding of the world. The data which we have on how electrons and atoms interact is gathered mostly on observations alone. For example, the properties of hydrogen atoms can distinguish between the different tissues and muscles within the human body, this is because the human body consists of 63% of hydrogen atoms and we learn all this data through the understanding of atomic particles. We can discover several ideas, if we continue with the research such as, new elements, their properties, amount of energy and how we could use that knowledge to our advantage.…
In 1879, Hertz solved the question posed by The University of Berlin’s philosophy department, that is, is electricity subject to inertia. For this he was awarded a gold medal and began to gain the recognition of other physicists…
Tesla's rotating magnetic field was once described as “ a thing that may be described, but not understood” Nikola Tesla was a brilliant scientist who had many great inventions that still have an effect on us today. His inventions such as the Tesla coil and AC electrical system make today's mechanical inventions function as well as they do. Tesla achieved his goals by believing in himself and his inventions, despite what anyone said. Tesla would have hundreds of trial and error before he would even come close to making improvements on his inventions. Tesla's determination inspires me and others to pursue and conquers our dreams.…
The upcoming technology will be microwave signals. Microwave signals is a type of electromagnetic power which works at extremely high frequencies. This kind of technology…
Another advanced technology tool is neuroimaging, which allows measuring activity in the deeper regions of the brain by detecting the amount of blood flow to different areas of the brain. Neuroimaging can be used in conditions such as obsessive-compulsive…
When they announced the new discovery, Percy Spencer accidently discovered that magnetron's property for heating food. That moment made him a great scientist and all the years of careful science was credited to…

More voltage causes more current which in return gives you a stronger magnet. If you were able to keep the electromagnet that you created in your laboratory activity, what would be two possible uses for the electromagnet? Pick up objects that have been dropped, to prevent bending over (maybe for a handicapped) and getting objects out of cabinets that are magnetic (again useful if handicapped) What is an advantage of using an electromagnet rather than a regular magnet?…
a century. This happened in the Moscow Engineering Physics Institute during splendid lectures given at that time by Professor D. A. Vasilkov. Even now I remember that feeling of delight and almost happiness. In the discussions with my classmates I rather heatedly insisted…
The contemporary physics revolution, based on the theory of relativity and quantum theory, has led science into a new era. Starting from this, human exploration has extended to the boundless universe, to the distant origin of the cosmos and to the microscopic structure of objects previously unknown to mankind. Contemporary physics revolution has also spurred revolution in life sciences and geosciences in the last years. All these have changed mankind's outlook on matter, time, space, life and the universe. Moreover, this contemporary physics revolution has also given birth to technological physics including nuclear energy, semiconductors, laser, new materials such as with superconductivity, and fostered rapid development of a wide range of new technologies that have changed the methods of our industrial production and our ways of…
