Testing the Strength of the Electromagnet by Changing the Number of Coils Aim The aim of this experiment is to investigate how the strength of an electromagnet is affected by the number of coil turns around the iron c-core. Hypothesis As the number of wire coils increases, the strength of the magnetic field (the electromagnet’s strength) will also increase. This means that the number of paper clips that attach to the electromagnet will increase. Explanation of Hypothesis/background: When

Copper Wire Subway. The Flaming Lizards Miranda Zuroske, Halie Lindberg, Maira Hernandez 2nd Hour The copper wire subway is a way to make great fun and somewhat simple way to show how a magnetized pull can move an object. Our objective is to make the battery strong enough with the magnetic pull of four magnets to propel it through a length of copper wire.

Introduction to Physics Lab (ZBT1) Electromagnetic Induction Marc Westover C164 ZBT1 Task 2 Professor Taha Mzoughi 03/14/2017 Introduction This experiment describes a physics lab on electromagnetic induction. It will test if coils of looped wire produce an electric current and if the number of coils makes a difference in a reading. The testing of electromagnetic induction goes back to 1831 with experiments conducted by Michael Faraday. His experiment led to one of the “basic laws of electromagnetism

of a bar magnet. An electromagnet is a magnet whose magnetic properties are produced by an electric current. When the current is switched off, the electromagnet no longer displays magnetic properties. Another definition for electromagnets are solenoids wound around a central iron core. The magnetic field generated by the coil of wire magnetizes the core, increasing the total field. The difference in simple terms: a solenoid is a long, thin helical loop of wire. An electromagnet is a magnet whose magnetic

Maglev trains are the technological breakthrough the 21 st century transport required. To keep up with the fast and unlimited demand of the global world, transportation methods need to be constantly updated. One of the greatest accomplishments of the Industrial Revolution in18th century Europe was the steam engine. The steam engine revolutionized transport. However, now with increasing population, costs, less space, and environmental issues, the current technology has become outdated and inefficient

I. “What hath God wrought?” This message, the first of its kind to be send instantly over a long distance was transmitted back in 1844. While it may seem insignificant, this series of clinks was what started the ear od communication. Morse code is a system created by Samuel F. B. Morse that uses dits and dahs sent over an electromagnetic box to relate messages. Throughout its growth, it has aided in many wars and led to new inventions like the radio and telephone. While it’s not used today, it’s

From the late 18th century to the early 19th century, the Industrial Revolution in the United States created advancements in the fields of manufacturing and technology. One of the most influential innovations that emerged from this period was the telegraph. Invented by Samuel F. B. Morse, the telegraph transformed how information was transmitted by allowing messages to be sent and received over long distances. The invention influenced many sectors of the economy, including warfare. Most significantly

painting. During his life Morse made several trips to Europe In 1832, while returning by ship from studying art in Europe, Morse considered the idea of an electric telegraph as the result of hearing a conversation about the newly discovered electromagnet. Although the idea of an electric

Samuel Morse was a very gifted man. He enrolled at Yale College and grew to love the lectures that Benjamin Silliman gave on electricity. He graduated with honors in 1810. Although Samuel liked to paint, he was discouraged from doing so by his father. Samuel Morse was a very influential man. The way he got involved in inventing the telegraph is both interesting and very sad. The invention of the telegraph was a long and strenuous process, he encountered many challenges throughout his journey with

The Impact of the Telegraph During the Industrial Revolution The telegraph was a major turning point in the 1840’s. Technology has come a long way since the early days of long distance communication. Today we carry around pocket-sized telephones, but in the past telecommunication technology was not so available. In the 1800’s messages had to be decoded using special symbols and language. Being able to send a message through a telegraph machine was not an easy task. Once the electric telegraph was

The word “copper” is an old Latin word meaning “cyprium,” after the island of Cyprus. Copper was named after the island Cyprus because it was where the Ancient Romans mined copper. Another name or copper is “Bronze Powder” or “Gold Bronze.” Copper is a reddish-brown metal and solid at normal room temperature. The metal is malleable, meaning that it was able to be bent and pounded into thin sheets. Furthermore, copper is ductile, in which it is able to be pulled and stretched into thin wire. The luster

Cell phones, microwaves, and even refrigerators are part of an average human’s daily life. These three items all use magnets. Magnets are used all the time in one’s normal day. The Earth itself is a magnet! (Blatt and Kendall). Magnets function through the North and South Pole. Each side has a positive and negative that either pushes or pulls depending on the charge it is reacting with. A North Pole (negative) repels another negative, but attracts a South Pole (positive). This is the same for a

One of his first discoveries was that the power of an electromagnet could be strengthened by tightly winding insulated wire around an iron core. He was also the first person to make a magnet that could lift 3,500 pounds of weight. He paved the way for discoveries by other inventors such as Michael Faraday and William

Intro: Speakers, the magical electronics that let you enjoy your favorite music. Such as “It’s Raining Men”. Without speakers, you won’t be able to enjoy your video games, your music, or talk to your friends through the web. How do these magical equipments actually work? It might surprise you how simple the mechanics of a speaker is. Curious yet? I will teach you about these 2 main topics, how sound works, and how speakers work. Speakers create sound waves, but what is sound? Inside the ear, there

it has "vocal cords." The vocal cords of the receiver are a diaphragm. Two magnets located at the edge of the diaphragm cause it to vibrate. One of the magnets is a permanent magnet that holds the diaphragm close to it.The other magnet is an electromagnet. It consists of a piece of iron with a coil of wire wound around it. When an electric current passes through the coil, the iron core becomes

What is Hydroelectric Power (H.E.P.)? Hydropower is the power/electricity, which is generated form energy of water flow. This source of power is considered to be renewable energy as it is constantly refilled due to the water cycle. In addition to the water cycle, hydropower is dependent upon stored gravitational energy. A rock on top of a hill contains potential energy because of its position. If a force pushes the rock, it rolls down the hill because of the force of gravity. Potential energy

Westinghouse and Edison: In the late 19th century, two of the world's famous inventors went head to head in a vicious public fight over electricity. The prize was the chance to light up the world and to make millions of dollars. Thomas Edison was the first to produce a range of motors and appliances requiring a DC current. , However Edison’s current could not be easily transported easily. Power plants needed to be located within 1 mile (approx. 1.6 Km) of the end user. (2012 The War of the Currents)

He had a big arc reactor to power the energy needs for the stark tower. While he was inside that cave, he made a small arc reactor that also acted as an electromagnet which functioned: to keep that shrapnel away from his heart and to power the first iron man suit. When he escaped from the cave, he created a new and better version of the arc reactor which is way more powerful than the previous one. However, this

painted some of the best portraits ever done by an American artist. In 1832, returning by ship from studying European art, Morse thought of the idea of an electric telegraph. He got the idea of the electric telegraph while thinking about the electromagnet. He probably made his first working model in 1835, but he was
