Draw a top-down diagram of your setup of image provided: I is current passing through wire arrows are vectors of compass pointing. This diagram should include: - The direction of current in the wires - The direction of the compass needle - Vectors representing the Earth's magnetic field and the magnetic field of the wire at the location of the compass - Known and relevant distances,angles, and currents - The cardinal directions (N,S,E,W) - Use your measurements from part E to calculate the strength of the Earth’s magnetic field. Show your work. Measurement: 2.5 current through wire pointing upwards (down to up), an angle the needle makes on compass (north pointing towards wire) when current is 2.5: 37degrees +/- 3. Distance of needle of compass to wire: 2.1 +/- 0.5 cm. hint: tan theta = B Earth/ wire. Calculate the uncertainty in your measurement of the Earth's magnetic field
Compare your measured magnetic field and uncertainty to the official range of values for the Earth's surface magnetic field . Are your measurements consistent with the official values?
