Explain How Strong Is The Magnetic Field Went The Length Of The Coil On Electromagnet

Explain how this lab helped you better understand the topics and concepts addressed this week.

With many schools experiencing budget issues or simply don’t have the room nor the ability to justify the extra expense of a science lab, many schools are looking online for virtual resources. The need to increase science literacy is almost a mandate from our dear president. This is a good thing, but the problem is people don’t want to spend money. NGSS demands more cognitive understanding of all sciences and engineering practices. Schools are looking to increase the level of science achievement of their students. Students generally found lab experiences valuable, and viewed lab experiences as beneficial to their learning. (Pyatt, 2012, p. 145)

The purpose of these experiments was to familiarize one’s self with laboratory equipment as well as becoming competent with different types of units as well as different methods of measurements.

Purpose: The purpose of this lab is to ensure that students are able to understand how to conduct measurements of length, mass, temperature, density and volume using different measuring devices. Students will also learn how to dilute substances by using simple algebra.

Universities and schools all over the country teach common core science, and many of the higher-grade classes work in a laboratory, as do many professionals who work in this field. Everyone who works or teaches in such an environment must be sure to take proper precautions, as they could be conducting dangerous experiments. Even if such precautions are taken, accidents do happen, sometimes lethal.

We also propose to use two meters of thick copper rather than one meter. The more material you have the more coils you will have around the ferromagnet. When we tested the number of coils around a ferromagnet, we found that no coils held 0 filings, fifty coils held 83 filings but 100 coils could hold 167 filings. Therefore the more wire you have, the more times you can coil the ferromagnet, which can make the strongest electromagnet.

In this graph, the magnetic field (B) is equal to 1/B. As displayed in the graph, 1/B is inversely proportional to the distance from the field sensor to the rod (R), which allows the graph to correspond to the expression of the magnitude of the magnetic field (B) in a current carrying wire when there is a change in distance. The current (I) remains constant in this part. Lastly, in part 2 of this lab, we analyzed the magnetic field of the magnet. Magnets can exert a force at a distance, just like electric charges. Magnetic fields permeate space and are strongest near a permanent magnet (magnetic dipole) or electromagnet (electric dipole); therefore, the power supply and ammeter were not required in this part. Part 2, consisted of determining the relationship between the magnetic field strength and the distance from the magnet. The graph 1/B vs. R^3, is the most linear out of the three. This graph corresponds the best to how we know a change in distance affects the magnetic field strength of a magnetic dipole, because the relatioship between a magnetic dipole and distance is inversely proportional. As the distance between the rod and the magnet increases, the magnetic field strength

are 3 key things to remember when it comes to magnetism and they are listed

It is usually represented by a combination of loops that leave the N-pole and enter the S-pole. These loops are called the magnetic flux. When a charge moves in an electric field, it will experience an electrostatic force given by an equation F=qE. Also, when a charge enters a magnetic field B, a magnetic force is exerted. F=qv*B. If the charge moves in a wire, with length L, the force can be represented as F=ILBsin(theta).

The use of MRI technology will increase in the United States and the world because of the tremendous significance in modern medical diagnosis. The Tesla Unit is a label on every MRI machine signifying the strength of the MRI Magnetic Field. The stronger the magnetic field, the

Since the 1700s scientist had been trying to use electricity to transmit intelligence, but a lack in fundamental knowledge stood in their way. Two developments in science finally made the goal seem achievable. Throughout 1800’s, Alessandro Volta 's invented the battery that made it possible to supply a steady electrical current. Later in 1820, Hans Christian Oersted discovered that a magnetic needle always tries to place itself at the right angles to a neighboring wire which is charged with a current of galvanic electricity. This was considered one of the best scientific discoveries since the construction of the voltaic pile. A few years later William Sturgeon invented the electromagnet by

Up until 1830’s it was difficult to measure the magnetic field of the earth quantitatively, due to there were no real standard to compare it against. Geologists in that era had difficulties on navigating from point A to point B [2]. As electromagnetic theory was industrialized through the 1800s, it was found that magnetic field strength could be given a definite value using coils which carries the current. In this EEi, the aim is to determine the measurement of the local magnetic field, comparing to a known value created by a coil known its size, current and turns. [1]

This lab is performed to analyze and understand Faraday 's law of electromagnetic induction and also its application in different magnetic components using Faraday 's Electromagnetic Lab simulation software 2.07. In this lab we understand the properties of the bar magnet, the basic electromagnet and also the electromagnetic induction in transformers. In the basic electromagnet, we observe the movement of the electronics both in AC and DC current source and compare the movement of electronics in those conditions. For better understanding of the electromagnetic induction in transformers, we observe the brightness of the bulb by changing the number of the loops in the coil, varying the magnitudes of the input ac current and also varying frequency.

Everything in the universe has its uses and abuses. The same applies to science. Science has revolutionized human existence and has made it happier and more comfortable. Modern science has many wonders. Electricity is one of its greatest wonders. It is a source of energy. It can run any type of machinery. With the help of electricity, we can light our rooms, run buses and trains and machinery, lift water for irrigation and can accomplish a multitude of other tasks.

Electromagnetism is the branch of physics that studies the relationship between electricity and magnetism. Electromagnets are magnets that uses an electric current to attract metal. Electromagnets have many parts that make up them and are used in many things.
