Tenets of a Technical Report Technical Reports are of various kinds. However, the following components are always prevalent and must be demonstrated in what constitutes “Technical Report” of any kind especially those that are: laboratory reports, case study reports and academic research studies. 1. Title of Paper or Report 2. Name(s) of Author(s) and their affiliations 3. Abstract or Executive Summary: brief report of the study objectives, approach utilized and the results got. 4. Introduction: should capture and highlight the goals, objectives and specific aims of a given study. 5. Literature Review: summary of what has been done and the results got or achieved by other people in a similar study. 6. Methodology: how the experiment was done or modified to achieve objectives. 7. Results and Discussion: results got, their comparison and evaluation with other similar work. 8. Conclusion: based on the accomplishment of objectives and evaluation results 9. References: literature referred to in the compilation of the report. 10. Acknowledgement(s): teams and individuals who helped in the accomplishment of the task. Experiment RTP-2 28 The Magnetic Field in a Coil When an electric current flows through a wire, a magnetic field is produced around the wire. The magnitude and direction of the field depends on the shape of the wire and the direction and magnitude of the current through the wire. If the wire is wrapped into a loop, the field near the center of the loop is perpendicular to the plane of the loop. When the wire is looped a number of times to form a coil, the magnetic field at the center increases. In this lab, you will examine how the magnetic field is related to both the number of turns in a coil and the current through the coil. A Magnetic Field Sensor will be used to detect the field at the center of the coil. A complication that must be considered is that the sensor will also detect the Earth's field and any local fields due to electric currents or some metals in the vicinity of the sensor. OBJECTIVES • Use a Magnetic Field Sensor to measure the field at the center of a coil. • Determine the relationship between magnetic field and the number of turns in a coil. Determine the relationship between magnetic field and the current in a coil. Explore the Earth's magnetic field in your room.

Connect the Vernier Magnetic Field Sensor to the Universal Lab Interface. Set the switch on the sensor to High 2. Using the long spool of wire, loop the wire ten times around a frame or box creating a coil of ten turns. Physics with Computers Experiment 28 3. Connect the coil, switch, ammeter, and power supply, as shown in Figure 1. 4. Prepare the computer for data collection by opening “Exp 28” from the Physics with Computers experiment files of Logger Pro. A graph will appear on the screen. The vertical axis has magnetic field scaled from 0.10 to +0.10 millitesla. The horizontal axis has time scaled from 0 to 20 s. The Meter window displays magnetic field in (mT). plane of PRELIMINARY QUESTIONS AND ADDITIONAL SETUP 1. Hold the plastic rod containing the Magnetic Field Sensor vertically and move it completely away from the coil. Click "Cobod to begin data collection. Rotate the rod around a vertical axis. Look at the graph. What do you observe? What is causing the variation of field reading? 2. Determine the orientation of the sensor when the loop magnetic field is at a maximum, and compare the direction that the dot on the sensor is pointing with the direction that the magnetic compass needle points. What did you discover? How much does the reading change in one rotation? 3. Set the power supply so that the current will be white sensor dot 3 A when the switch is closed. Place the sensor in aligned with coil center magnetic a vertical position at the center of the coil, with field sensor the white dot facing along the axis of the coil as shown here. Click Collect Wait 2 to 3 seconds and then close the switch. What did you observe? Warning This lab requires fairly large currents to flow through the wires. Do not leave the switch on except when taking measurements. The coil wire and possibly the power supply may get hot if you leave current flowing continuously. 4. Repeat Step 3, but this time rotate the Magnetic Side View of Coil Field Sensor while you are holding the switch closed. Determine the orientation of the sensor that gives the maximum reading. How much does the reading change in one rotation of the sensor? PROCEDURE Part! How Is The Magnetic Field In A Coil Related To The Current? For the first part of the experiment you will determine the relationship between the magnetic field in the center of a coil and the current through the coil. Use the loop with all ten turns for all of Part I. As before, leave the current off except when making a measurement. 1. Set the power supply so that the current will be 3 A when the switch is closed. 2. Place the Magnetic Field Sensor in a vertical position so that the flat end is at the center of the coil. With the switch closed, rotate the sensor about a vertical axis and observe the magnetic field values in the Meter window. Find the position that indicates a maximum positive magnetic field. The flat end of the sensor should be in the plane of the coil. Keep the sensor in the same position for the remainder of the experiment. 3. We will first zero the sensor when no current is flowing; that is, we will remove the effect of the Earth's magnetic field and any local magnetism. With the switch open, click Zero 28 - 2 THE MAGNETIC FIELD IN A COIL RTP -2 Experiment 28 Supplement CAUTION DO NOT UNWIND THE COILS ON THE CYLINDER Procedure Please become familiar with the lab experiments“ RTP-2 The Magnetic field in a coil” and the revision procedure. Check the wiring of the laboratory equipment, before proceeding with the experiment. The laboratory apparatus for the "Magnetic Field in the coil” experiment consist of a cylinder upon which ten separate coils are wound. The coils vary from one turn to ten turns. To activate the coils, place the red alligator clip lead, marked "Coils select", to the desire terminal. On the board marked 1s through 10th. Turn the switch marked “SW” to the “on” position. Adjust the power supply to the current output on the amp meter as required for the experiment. Proceed with the instructions in the experiment procedure. It is important that the sensor probe be place within the coil at the position that corresponds to the “coil select" position. Example: Coil select position 6t should correspond to 6t on the coil holder.

The Magnetic Field in a Coil
Abstract/Executive Summary
This experiment was carried out to determine various factors involving generating
magnetic fields using wires and coils. The objectives were as follows:
-

To learn how to use a magnetic field sensor to measure the field generated at the center of
a coil that has current passing through it

-

To examine how the magnetic field and the number of turns in a coil affect each other
and to determine their relationship.

-

To determine how magnetic field and the current in the coil affect each other and to come
up with their mathematical relationship

-

To appreciate the existence of the earth’s magnetic field and to observe its effect and
significance.

The results obtained from this experiment, hopefully, should be as those expected and
learned in theory. Errors are highly likely as the results obtained highly depend on the sensitivity
of the measuring equipment, the accuracy of the one carrying out the experiment, and the ability
to minimize errors caused by uncontrollable external factors such as the earth’s magnetic field.

THE MAGNETIC FIELD IN A COIL

Introduction
Whenever one passes a current through a conductor, the result is that a magnetic field is
formed just around the wire. The strength of the field, which is measured in Tesla, depends on
the amount of current passed. The more the current, the stronger the field. The direction of the
field can be determined using various laws. According to these laws, the direction of the field
depends on direction of current through it. The shape of the wire also tends to influence the
strength of the magnetic field.
The wire can then be wound to form a loop. If this is done...
