CSU Physics Magnetic Fields Relevance to Everyday Life Discussion
Lets take a break from all of the book learning and explore the world around you. For these assignments, your writing will be focused on Everyday Physics which will help you connect your Readings to things that have happened in the world around you. In this module, you will look for an article or news story/video that relates to one or more of the following topics:These are pretty broad topics, but a few ideas should spring readily to mind. Create a thread post including one or more of the topics listed above, an active hyperlink to your resource (this resource cannot be used by another student), a summary of the resource itself, a summary of the material you are learning in this module as it relates to your resource (cite portions of the textbook), and an explanation of how the topic or resource ties to your everyday life. Then provide a substantive reply to at least two of your classmates posts:First postHello class!The inductor was invented in the 1800s by an English scientist named Michael Faraday. This week I have chosen an article that discusses the role inductors play in electronics such as power supplies. The article discusses that inductors consist of insulated wire that is commonly wound into a coil. Inductors come in many different shapes such as circular and rectangular shapes. They also contain a magnetic wire that prevents the risk of shortages that may be caused by the inductor. Inductors are produced with precious conductive materials such as copper and iron which makes them relatively expensive. Inductors are used in power supplies to prevent any quick or sudden changes in current and the output of voltage. Our textbook on page 937 states “An inductor acts to oppose changes in the current through it”. Also, the textbook states “An inductor is a device that can be used to produce a known magnetic field in a specified region.”. In concluding our textbook’s statements, an inductor works by storing emf and then releasing it back into the circuit to prevent a spike in current and to try and regulate the current back to normal. Inductors can be found in a plethora of other electronics such as televisions, radios, and telecommunication equipment, and serves the same function as their application in power supplies. Inductors are simple components but are still very fundamental in the field of electronic design, without inductors we may not have many of the modern electronics that we use on a daily basis. Second postTransformers in Aviation Transformers are devices that facilitate the transfer of electrical energy between different voltage levels. They operate on the principle of electromagnetic induction, where the changing magnetic field generated by alternating current (AC) in the primary coil induces a voltage in the secondary coil.In a transformer, there are two coils of wire, the primary coil and the secondary coil, which are wound around a shared iron core. The primary coil is connected to the power source, while the secondary coil is connected to the load or the device that requires electrical energy. When AC flows through the primary coil, it creates an alternating magnetic field in the iron core.This changing magnetic field induces a voltage in the secondary coil through electromagnetic induction. The voltage induced in the secondary coil depends on the turns ratio between the primary and secondary coils. By varying the number of turns in each coil, transformers can step up or step down the voltage.Step-up transformers increase the voltage from the primary to the secondary coil. They have a higher number of turns in the secondary coil, resulting in an increased voltage output. Step-down transformers, on the other hand, decrease the voltage from the primary to the secondary coil. They have fewer turns in the secondary coil, resulting in a reduced voltage output.The ability to change voltage levels is what makes transformers essential in various applications, including aviation. Transformers are used to convert high voltage power generated by power stations to lower voltage levels suitable for homes, businesses, and different electrical devices. They ensure efficient power distribution, minimize energy losses, and match the voltage requirements of specific systems or components.In aviation, transformers are utilized for tasks such as voltage conversion, power distribution, and regulation. They play a crucial role in adapting power supply characteristics to meet the specific requirements of various aircraft systems, including lighting, communication, avionics, and more. Transformers contribute to reliable power delivery, optimal system performance, and overall safety in aviation applications.
