April 30 around 7:45pm. This was the day we all got into our groups and did different experiments with the probe, circuits, etc. So I just included what experiment I did and included details and data. Hope this is okay! VERY INTERESTING EXPERIMENT!
110413 Physics IIThis day we got into groups of two and all did different experiments. I measured motion(m) vs. magnetic field(mT) with the probe, magnet, and ruler.
When holding the probe on the rectangular magnet at the two ends and middle, I got: 5.65, 5.715, and -7.984.
If you flip the probe, the magnetic field jumps. One side of the probe measured (5.57) while if you flipped it 180 degrees, I got a measurement of (-7.982), when held on the magnet.
Here’s my data when the probe was held PERPENDICULAR to the ruler:
0cm: -7.969
5cm: -2.08
10cm: -0.15
15cm: 0.135
20cm: 0.22
25cm: 0.24
30cm: 0.258
35cm: 0.26
VERY INTERESTING! I noticed that the further away it got from the magnet, it decreased in the amount of change.
I also did another “experiment” where I used the ends of the magnet, moving the probe away.
Here’s my data with that:
0cm: -3.46
5cm: 0.23
10cm: 0.258
15cm: 0.27
20cm: 0.276
25cm: 0.28
30cm: 0.282
35cm: 0.287
I graphed 4 different graphs using this experiment:
Magnetic field (0.1 to 5.8mT) vs. motion (0.18 to 1.48m) This one starts out constant then jumps, increasing at an increasing rate.
Magnetic field (0.1 to 5.8mT) vs. time (0 to 15sec) This one starts out decreasing right off and comes to a leveling line.
Motion (0.1 to 0.5m) vs. magnetic field (0 to 5.8mT) This one starts out jumping at an increasing rate and slowly turns into a leveling line, also.
Motion (0.1 to 0.5m) vs. time (0 to 15sec) This one decreases at a pretty steady rate.
These graphs were SO interesting and I learned so much from doing this particular experiment in class! It was also neat to see the other groups circuits and experiments they were doing.
&#Good responses. Let me know if you have questions. &#
