The Electromagnetic Spectrum

- PART 1 The Electromagnetic Spectrum is the range of frequencies of possible electromagnetic radiation. The Spectrum ranges from 0 Hertz up to 2.4x1023 Hertz. The exact wavelength limits of the Spectrum are unknown however it is widely believed that the short wavelength limit is equal to the Planck Length (1.616x10-35m) and the long wavelength limit is the length of the Universe. Electromagnetic radiation (EMR) is an occurrence that takes the form of self-propagating waves produced by the motion of electrically charged particles, which can move through matter or a vacuum....   [tags: Physics]

Electromagnetic Induction

- Michael Faraday was a chemist and physicist from England. He invented electromagnetic induction in 1831. Electromagnetic induction as defined by Stuart Bushong is: An electric current is induced in a circuit if some part of that circuit is in a changing magnetic field. This observation is summarized in what is called Faraday’s Law, or the first law of electromagnetics. After a series of different experiments, Faraday determined that an electrical current cannot exist just by the presence of a magnetic field....   [tags: Medical Technology ]

Electromagnetic technology is extremely complex and because it is an electromagnet, the higher the current, the stronger it becomes, and with this an electromagnet can become incomprehensively strong....   [tags: Papers]

Magnets and Electromagnets

- Introduction Magnets have existed for hundreds of thousands of years and have been used by many different cultures throughout this time. Magnets have been useful throughout the years because they can hold two things together just through the force of the metal in the magnet. With the world’s constantly changing technology, electromagnets have been evolved from magnets and are more useful than a regular magnet but in order for an electromagnet to work, an electric current needs to be present (   [tags: Physics, Magnestism]

Electromagnet Investigation

- Electromagnet Investigation An electromagnet works similarly to a normal magnet but with one huge advantage. A normal magnet is constantly on but an electromagnet can be turned on and off. This is useful in both the science lab and industry such as a scrap yard. An industrial investigation of this size is obviously not possible in the science lab so in order to simulate a smaller type of situation I'm going to use small weights. I plan to find out the different characteristics of an electromagnet by changing the number of coils around the electromagnet and the amount of current which is passed through it....   [tags: Papers]

Michael Faraday's Contributions to Science

- The person who changed the history was a guy named, Michael Faraday who was an English scientist. He was the mastermind who conducted three investigations which are very interesting to us. The most important investigations to us are from the fields of electromagnetism and electrochemistry. He brought together the three lines of inquiry, matter, light and electricity which later became known as electromagnetic induction, diamagnetism electrolysis. This brilliant guy started with electrical conduction in liquids, even though others already begun to study electrolysis but because of his organized and cautious measurements that we know the laws undergoing electrolysis....   [tags: electromagnetism, cathodes, glow]

The Magnetic Fields Of The Magnet

- Introduction: Magnetism was not studied or utilized before 1821 as it is today. A few hundred years ago people understood how magnets worked, but didn’t have many applications of the magnet because they were limited by the technology of their time. The applications of magnets today have opened a new door as to how we can harness the power of a magnet. I had a basic working knowledge of how magnets worked, such as polarity, but with researching different aspects of the magnet I have learned that we need to advance the potential capabilities of the magnet and fully understand how we can harness the magnet....   [tags: Magnetic field, Electromagnetism, Magnetism]
