Our Experiment<br />
Purpose:<br />
Measure the earth’s<br />
magnetic field by<br />
comparing two<br />
different methods:<br />
1. EM induction<br />
2. The theory of change<br />
in magnetic flux.
Background Info<br />
EM induction<br />
- “Loop” of wire<br />
- When cutting through magnetic field lines,<br />
current is induced through the wire<br />
- Current measurable with lab pro<br />
Magnetic flux<br />
-Sensor<br />
- Picks up interference between magnetic field<br />
lines<br />
- Voltage change recorded
Hypotheses<br />
�Tesla’s theory of EM induction<br />
�E=blv<br />
�Accurate results?<br />
�Field Strength v. Altitude<br />
�As altitude increases, the strength of the<br />
magnetic field decreases.
Preliminary Testing<br />
still, white dot<br />
facing down<br />
Moved it to the left,<br />
facing down<br />
Moved it right,<br />
facing down<br />
Jostled<br />
consistently
Trial 1
Trial 2
Trial 3
Analysis<br />
�7.19EE-5 Teslas 43.8% error<br />
�Reasons for error:<br />
�Wind Current<br />
�Low Tolerance of equipment<br />
�Human Error
Conclusion<br />
�Found strong evidence for Tesla’s theory<br />
of EM induction using earth’s magnetic<br />
field.<br />
�Constant rotation is not necessary to<br />
induce voltage, although constant rotation<br />
would create more accurate results.<br />
�Steady decline in magnetic field intensity<br />
with altitude increase.
