Analyses:
1. What do you notice about the trend in your graph from Table 1?
The trend in the graph from Table 1 shows that as the horizontal position d increases,
the magnetic field B slightly decreases. The points on the graph are close to each other,
indicating a very small change in the magnetic field.
2. What do you notice about the trend in your graph from Table 2?
The trend in the graph from Table 2 shows that as the current I increases, the magnetic
field B also decreases. This decrease is more noticeable and forms a clear, almost
straight downward line on the graph.
3. As you increase the current, the circles around the wire get darker. What does this
indicate?
As you increase the current, the circles around the wire getting darker indicates that the
magnetic field strength is increasing. This means a stronger current produces a stronger
magnetic field around the wire.
Summary and conclusions:
In the first graph from Table 1, we observed the relationship between the horizontal position
d and the magnetic field B. The data showed that as the horizontal position increased, the
magnetic field slightly decreased. This trend was very subtle, meaning the magnetic field
didn't change much with the position. The points were close to each other, indicating a small
variation in the magnetic field along the horizontal distance.
In the second graph from Table 2, we looked at the relationship between the current I and the
magnetic field B. This graph showed a more noticeable trend where increasing the current
led to a significant decrease in the magnetic field. The points formed a clear downward line,
suggesting a strong inverse relationship between the current and the magnetic field strength.
This means that as we increased the current, the magnetic field became stronger around the
wire, as indicated by the darker circles.
From the analysis of both graphs, we conclude that the magnetic field is influenced
differently by horizontal position and current. The position has a minor effect, causing only a
slight change in the magnetic field. On the other hand, the current has a more significant
impact, where increasing the current leads to a stronger magnetic field around the wire. This
demonstrates the direct relationship between electric current and magnetic field strength, a
fundamental concept in electromagnetism. Understanding these relationships helps us
comprehend how magnetic fields behave in various situations and can be useful in practical
applications such as designing electromagnets and electric circuits.
