During field vs. distance graph was produced

During this
lab experiment, we used four different electrical components to determine the
electrical field. We used a power supply, a Vernier magnetic field sensor,
magnetic field coils and the logger pro software to help us record and graph
all our results. We began the experiment by ensuring that all components such
as the electrical cables were properly connected in the desired configuration. The
first part of the experiment was done by the TA as a demonstration of how to use the equipment
including using certain features of the LoggerPro software. First, the long
straight conductor was connected to the power supply. The power supple was set
to a current of 7A and the sensor to a 0.3mT range and in the bent position.
Starting from 2cm away from the conductor, the sensor was moved in increments
of 1cm for a total of 5 trials. Each trial was recorded on LoggerPro by
clicking the ‘collect’ button to determine the relationship between the magnetic field
of a straight conductor. A field vs. distance graph was produced to further
help visually represent the relationship.

For
the second part of the experiment, we found the magnetic field at the centre of
a single coil. We began by setting the single coil current on the LoggerPro
interface. As a safety precaution, we turned the power supply off to connect a
single coil with the proper electric cable. We then set the sensor to the 6.4mT
range and in the unbent configuration while also positioning the ruler and
retort stand such that it passes through the single coil just below the centre
axis. With steady hand, we help the probe sensor on top of the ruler so that it
is positioned properly at the centre of the coil. Using LoggerPro, we collected
the magnetic field values for the electric current in decreasing increments of
0.4A starting from 2A. The results were recorded to the table left of LoggerPro
which then produced a graph. Finally, we determined the relationship between
the magnetic field of a single coil and the electric current by obtaining a
linear fit for the graph.

For
the third part of the experiment, we found the magnetic field along the central
axis of a single coil. With the single coil still connected, we set the power
supple back to 2A. We took measurements of the magnetic field along the central
axis in decreasing increments of 3cm starting at 24cm. Similar to part two, all
results were recorded on the table on LoggerPro to produce a graph and curve
fit.

For
the final part of the experiment, we found the magnetic field of two coils. We
positioned two coils so that they are parallel with one another and within the
rectangular outlines of the base. The two coils were then connected properly
using the appropriate electric cables and ensured that the coils are correctly
configured using the right-hand rule. The power supply was set to an output of
1A current. We took measurements of the magnetic fields across both coils in
increments of 5cm starting from 15cm. Similar to part three, we recorded all
results to LoggerPro to produce a curve fit.
