Lab Report On Magnetic Fields

The white lead of the needle faces the South part of the magnet in a perpendicular way. When the needle is facing the center of the magnet, the lead turns to a 90 degree angle, being parallel to the magnet. When the compass faces the North part of the magnet, the needle turns 90 degrees in the same direction until the red lead if facing towards the North of the magnet.

14. Calculate the volume of the magnet by multiplying the length × width × height, record in Data Table 5.

5) Based on our assumption, we believe that the Mean multiple would be the best measurement for calculating Hertz Terminal Value.

5. At a coil current of 3 A, what is the magnetic field produced at the center of the Helmoltz coils in gauss? About what is the magnitude of the Earth’s field in gauss?

If they do not, but are within the acceptable margin of error of ±20√4=±40’’, each angle is corrected to create a sum of 360˚. For this project, the angles added to 360˚ 00’ 10’’. After each angle is corrected, angle 412 is 78˚31’03’’, angle 123 is 99˚01’23’’, angle 234 is 92˚32’21’’, and angle 341 is 89˚53’13’’. After using the Total Station, the Auto level is used to measure the elevations of each point. The known elevation outside of Powell is 380’. The Auto level is placed between each point to measure the backsight and foresight. Once all the points are measured, all the backsights and foresights can be measured with the difference taken to find the error. With this project, the error was -0.128’. Next, the pacing between each point must be taken to find the correction for each elevation with the equation, (distance from known elevation/total level network distance) X total error. The total pacing for the project is 235 steps with a pace of 2.31 feet per step. After the corrections, point 4 is 379.384’, point 3 is 378.182’, point 2 is 379.093’, and point 1 is 379.645’. A transit is used to find the true north from the magnetic

In Lab 8, the time constant of resistance-capacitance was measured in order to determine the charge of a capacitor. This experiment was conducted by setting building a circuit that connects the voltmeter across the resistor. The voltmeter was then connected across the capacitor. The above procedure was conducted several times using different voltages. Afterwards, the results were calculated and tabulated. The data obtained from the lab were the theoretical Tau for 5V, 4V and 3V. In this experiment, the calculated voltage was also determined. The theoretical and the calculated values were then compared and evaluated by determining their percentage errors. For example, in the 5V, the theoretical value was 1.23V; calculated value was 1.434 with a percentage error of 16.6 %( for voltmeter across capacitor).

The most profound finding of this experiment is that the inductance of the secondary coil does not influence the overall performance of the system in a real-world scenario. The factor that influenced the real-world performance most is the total resistance/loss in the secondary, which is shown by an inversely proportional relationship. As the effective resistance of the secondary coil decreased, its performance went up, as shown by the trend lines in Graphs 1 and 4.

The gradient coils generate a secondary magnetic field to enable images directionally in the z, x, y planes. These are

In TLS storage ring corrector magnet power supplies major work is used to correction the magnet filed direction of electronic beam track. Those need high precision satiable output current of magnet power supply. In Fig. 1shown, the correction power converter module with power system rack, which could be operation eight piece power converter modules by control the MCOR 12/30A single ended analog signal interface card as shown Fig. 2. Those inner circuits had the bi-directional analogy buffer and isolate circuit used to protection analogy signal of MPS.

6) Change the location of the positive charge to at least six widely different distances from the equipotential sensor. Record the voltage reading and distance at each location.

By using a twister pair of wires the electromagnetic signals generated by the wires cancel each other out due to their opposite polarity.

Theoretical analysis is one of the most significant phases of the project. The high resistance measurement system developed during this project is primarily based

Change the location of the positive charge to at least six widely different distances from the equipotential sensor. Record the voltage reading and distance at each location.

In preparation of this lab, a slinky (treated as a solenoid) with 80 rings was stretched to a length of 1.5 m, producing a coil density of 53.333 rings/m and taped at both ends of the solenoid onto a lab bench. An adjustable power supply was connected to insertable positive and negative ends of the alligator plugs. The two alligator wires were coloured black and red, the black wire was connected to the negative end while the red wire was connected to the positive end. The alligator heads were then clipped onto the ends of the solenoid to create a flowing current and a magnetic field. The magnetic field Vernier sensor, set to the lowest magnetic field range, connected to a LabQuest Mini and was placed in the center of the solenoid and rested

One can interpret these lines as indicating the direction that a compass needle will point if placed at that position.
