Overview:
In this experiment, we learned about Faraway’s Law which states that changing magnetic fluxes through coiled wires generate electricity (currents and voltage). We shook a tube which has a magnet that will travel back and forth through a coil of wires. We will be showing that the faster we shake the tube, the greater will be the generated voltage.
Apparatus
- usb
- generator
- battery
- voltage probe
Procedure:
- We shook the tube at a particular rate.
- Counted the number of shakes.
- Find the sum of squares of the voltages (SSQV). (voltage logged after each second on the Excel)
- Repeated steps 1-3 with 3 different rates of shakes.
- Plotted the SSQV’s as a function of # of shakes and fit the result to a linear curve.
Data:
# of Shakes | Sum of Squares of voltages (SSQV) |
0 | 0.473078531 |
28 | 12.88478037 |
37 | 14.52086454 |
60 | 31.35522 |
Interpretation:
As the number of shakes increases, the sumsq of voltage increases as well.
