    Electromagnetic Induction The phenomenon called electromagnetic induction was first noticed and investigated by Michael Faraday, in 1831. Electromagnetic induction is the production of an electromotive force (emf) in a conductor as a result of a changing magnetic field about the conductor and is a very important concept. Faraday discovered that, whenever the magnetic field about an electromagnet was made to grow and collapse by closing and opening the electric circuit of which it was a part, an

    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

    The electromagnetic spectrum is the range of all electromagnetic radiation. The electromagnetic radiation can be radio waves that we use to listen to music, visible light that we use to see or microwaves that we use to cook food with. We deal with all of these types of radiations in our daily lives. RADIO WAVES: Radio waves are used exactly for what it says — radio. They are also the waves responsible for the signals cell phones and televisions receive. Objects in space, such as planets and comets

    Electromagnetic Radiation and Its Effect on the Human Body In 1998 a Maryland neurologist, Dr. Christopher Newman, was diagnosed with brain cancer and he could no longer work as a result of his disease. He claimed that the Motorola cell phone he had in 1992 to keep in touch with his patients gave him cancer. Then in 2000, he filed an $800 million lawsuit against several wireless providers including Motorola Inc., Verizon Communications Corp., Bell Atlantic Mobile Systems, and others. Within a month

  • The Importance Of Electromagnetic Waves

    1275 Words  | 3 Pages

    INTRODUCTION Electromagnetic waves propagate in waves with several measurable characters, namely: wavelength, amplitude and speed frequency. The amplitude is the wave height, whereas the wavelength is the distance between the two peaks. The frequency is the sum waves passing through a single point in a single unit of time. The frequency depends on the speed of wave propagation. hence, the speed of the electromagnetic energy is constant. Electromagnetic energy has a very important role in everyday

    The electromagnetic spectrum is all around us and serves many beneficial and lifesaving purposes every day. There is no escaping it, because much of the spectrum cannot be seen. We can tell it has taken place by getting a tan or sunburn or by the fact that our plants and flowers thrive and grow. This includes x-rays, gamma rays, visible, ultraviolet, infrared light, radio waves and microwaves. While it has many useful purposes, it can also have many negative consequences due to overexposure, some

  • The Dangers of Electromagnetic Fields

    1048 Words  | 3 Pages

    The dangers of the electromagnetic can be low on danger and high on danger. Depending on the amount of how much the body absorbs verifies the lethality of the EMFs. Humans are extremely sensitive to EMFs. Yes if a person absorbs too much energy it can lead potential to death, but if they absorb small portions it can lead can lead to nausea, paranoia, and many more small affects. The US National Institute for Occupational Safety and Health (NIOSH) has issued cautionary advisories on EMFs. Everyone

  • The Pros And Cons Of Electromagnetic Energy

    1078 Words  | 3 Pages

    We depend on electromagnetic energy every moment of our lives, from watching tv to microwaving our food, without it our world would not be the same. Electromagnetic energy travels in waves, and has a very large range from long radio waves to very short gamma rays called the electromagnetic spectrum. The electromagnetic spectrum is the distribution of electromagnetic radiation according to energy, frequency or wavelength. From radio waves to gamma rays there are 7 types of lights most not visible

  • Electromagnetic Spectrum Essay

    2005 Words  | 5 Pages

    Spectrum refers to the electromagnetic spectrum, which is the range of frequencies through which electromagnetic radiation travels. Electromagnetic radiation is the energy that travels at the speed of light in waves as a stream of photon particles. This form of energy encompasses radio waves, microwaves, visible, nonvisible light, X–rays and gamma rays, and these classifications are based upon the frequency at which the energy travels (see figure 1). In order to refer to a specific portion, also

  • Reflection Of Electromagnetic Radiation

    Introduction to light: Electromagnetic radiation is a form of light energy. Electromagnetic is made up of visible light, invisible light (ultraviolet, infrared, X-rays, radio waves and microwaves). In vacuum lights maximum velocity is 3.0x10^8 m/s. Reflection: If an object does not radiate its own light, it must reflect light to be visible. Reflection includes two beams - an approaching or incident beam and an active or reflected beam. The imaginary line that is perpendicular to the principal axis

    Electromagnetic Spectrum for the Middle School Student Waves are all around us and come in various forms. Sound waves can travel through air because air is made of molecules, which carry the sound. Another type of wave is electromagnetic waves, which are different than sound waves because they don’t need molecules to travel. This means that electromagnetic waves can travel through air and solid materials as well as empty space (Groleau 2011). The electromagnetic spectrum consists of all waves

    The electromagnetic spectrum is a range of different types of radiations, this is energy that travels and spreads out as it goes. This range involves more than just visible light- small portion of the spectrum detected by the human eye- it goes beyond what the human eye cannot see. The two most important characteristics of the spectrum are wavelength and frequency. The electromagnetic spectrum can be divided into three different parts: the theory of visible light, the range of the electromagnetic

    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

    Electromagnetic Wave 1.Definition of Electromagnetic Waves. Electromagnetic waves are waves that can propagate even though there is no medium. A magnetic field that changes with time can generate an electric field that also changes with time, and an electric field that changes with time can also produce a magnetic field. If the process is continuous it will produce a magnetic field and electric field continuously. If these magnetic fields and electric fields simultaneously propagate (spread) in

    Michael Faraday is a British physicist and chemist, best known for his discoveries of electromagnetic induction and of the laws of electrolysis. He was born in 1791 to a poor family in London, Michael Faraday was extremely curious, questioning everything. He felt an urgent need to know more. At age 13, he became an errand boy for a bookbinding shop in London. He read every book that he bound, and decided that one day he would write a book of his own. He became interested in the concept of energy
