TUTOR WHO HAS FORCE SENSOR ON HAND (I PERFORMED THIS EXPERIMENT BUT LOST ALL THE PHOTOS AND NO LONGER HAVE THE FORCE SENSOR I BORROWED AND NEED TO TURN IN ASAP) Here is my lab report, I already did the experiment but if ur bale to could grab some things to make a brief example of experiment because I lost my photos.

THE RELATIONSHIP BETWEEN DISTANCE AND FORCE OF ATTRACTIONS IN MAGNETS LAB

Hallie Hadi, Mrs. Vilcan, Physics Honors, 05/2023

1Purpose

To investigate the relationship between the distance between two magnets and the force of attraction between them.

2Hypothesis

If the distance between two magnets is decreased, then the force of attraction between them will increase.

3Variables

Independent variable: Distance between the two magnets (5cm, 10cm, 15cm, 20cm)

Dependent variable: Force of attraction between the two magnets (measured in Newtons)

Control variables: Type of magnet, height of the magnets, temperature

4Materials

2 magnets

Force sensor

Table

String

5Procedure

1. Tie a string to one magnet and hang it from the edge of a table.

2. Place the other magnet on the table, making sure it is at the same height as the hanging magnet.

3. Set up the force sensor according to the manufacturer's instructions

4. Calibrate the force sensor as per the manufacturer's guidelines.

5. Measure the distance between the two magnets using a ruler.

6. Slowly bring the magnet on the table closer to the hanging magnet until they attract and the force sensor registers a force reading.

7. Record the force reading in Newtons.

8. Repeat steps 5-7 for each distance (5cm, 10cm, 15cm, 20cm) for a total of 3 trials.

9. Record data.

10. Graph results and analyze data.

6Data Observations

Distance vs. Force of Attraction

| Distance (cm) | Trial 1 Force (N) | Trial 2 Force (N) | Trial 3 Force (N) | Average Force (N) |

| 5 | 0.72 | 0.68 | 0.74 | 0.71 |

| 10 | 0.41 | 0.40 | 0.39 | 0.40 |

| 15 | 0.24 | 0.25 | 0.23 | 0.24 |

| 20 | 0.16 | 0.17 | 0.18 | 0.17 |

7Results

The data collected shows that there is an inverse relationship between the distance between magnets and the force of attraction. As the distance increases, the force of attraction decreases, which aligns with my hypothesis. The data is reliable and consistent, with no notable anomalies or outliers. The force values obtained from each trial for a given distance are relatively close to each other, indicating good precision in the measurements.. The observations support my hypothesis that a decrease in distance between magnets results in an increase in the force of attraction between them, which aligns with the fundamental principles of magnetism.

8Conclusion

The experiment's goal was to learn more about how the force of attraction between two magnets and their distance from one another relate to one another. The following conclusions can be made based on the results attained:

The findings of the experiment provide solid evidence in favor of the hypothesis that when the distance is decreased between two magnets, their attraction would grow stronger. The data repeatedly showed that the force of attraction and distance are inversely related. The force of attraction diminished as the gap between the magnets widened. As an illustration, at a distance of 5 cm, the average force of attraction was 0.71 N, whereas at a distance of 20 cm, it was just 0.17 N. These results support the basic principle of magnetism, which states that stronger magnetic attraction occurs with closer proximity between magnets.

The results align with my understanding of magnetic interactions and contribute to scientific knowledge in the field of magnetism. The experiment was carefully carried out to ensure the accuracy of the results. However, the experiment has limits, and further research with various types of magnets and a wider range of distances is needed for better knowledge.

9Future Recommendations

Expanded Distance Range:Test a wider range of distances to gain a more comprehensive understanding of how the force of attraction changes with varying distances.

Varied Magnet Types:Experiment with different types of magnets, such as electromagnets to compare their force of attraction at different distances. Investigate the effect of magnet shape and size on the force of attraction.

Temperature Variation: Investigate the influence of temperature on the force of attraction between magnets. Repeat the experiment at different temperatures to observe any temperature-dependent changes in magnetic attraction.

Gather the materials needed for the experiment:

• Two magnets of the same type
• A force sensor
• A table or flat surface
• A string
• A ruler or measuring tape

Tie a string to one of the magnets. Make sure the string is long enough to allow the magnet to hang freely from the edge of the table.

Place the other magnet on the table, ensuring that it is at the same height as the hanging magnet. You can use a support or adjust the height of the table if needed.

Set up the force sensor according to the manufacturer's instructions. Connect it to a data acquisition system or interface if necessary.

Calibrate the force sensor as per the manufacturer's guidelines to ensure accurate measurements.

Measure and record the initial distance between the two magnets using a ruler or measuring tape. This will be your starting distance.

Hang the magnet with the attached string from the edge of the table, allowing it to hang freely.

Slowly bring the magnet on the table closer to the hanging magnet until they attract each other. Ensure that the force sensor registers a force reading when the magnets come into contact.

Record the force reading displayed on the force sensor. This represents the force of attraction between the magnets at the given distance.

Repeat steps for each desired distance, such as 10cm, 15cm, and 20cm. Ensure that you conduct multiple trials for each distance to obtain reliable data. CAPTURE TWO IMAGES
