PHYS 1010- Lab 4 Magnetism Experiment-1 Material required: 1) IO lab device 2) Compass (Phone) Procedure: I began the experiment by starting the IOLab, calibrated it and took measurements of the places and orientations specified in the Lab Handout. I quickly determined the direction of magnetic north using the compass app on my iPhone. I moved the phone to several areas, including the floor, top shelf, and table, to see if the magnetic field varied across the space, as seen in the photos pasted. I saw the magnetic field was constant throughout the room. After that, I tried to determine where in the room would be best to compute the earth's magnetic field. I was able to find the room's latitude and longitude using the provided link, and the compass app also showed these coordinates.
Result:
Conclusion: The magnetic field changed as I moved the gadget around my room and set it in different locations. The IOLab's location parallel to the table's north pole yielded the strongest field readings. I believe that the electrical setup in the space has an impact on the magnetic field measurements made by the IOLab. Even though there are large discrepancies between my IOLab measurements and the earth's magnetic field, each estimate is within the range of error. The NOAA's magnetic field estimate also showed a noticeable error, but the z- component of both readings varied the most. The vector equation for the magnetic field with the y-axis of the IOLab aligned with the magnetic north is (49.76)i + (26.9)j - (215.43)z. Experiment-2 Material Required: 1) IO Lab Device 2) Alligator clip 3) Tape 4) AA and AAA cell Procedure: One of the alligator-clip wires should be used to create a circle that is as round as feasible. Hold the loop in position while measuring its radius using tape or a clip. To start recording

data on the IOLab app, position the loop squarely over the magnetic sensor and attach one end of the wire to the negative terminal of the battery. Connect the opposing end of the wire to the battery's positive terminal. Repeat the test two or three times, changing the loop's radius or number of circles each time. Result: Loop 1 ( Radius = 1.5cm) Loop 2 (radius = 1.5cm)
Loop 3 (radius = 1.5cm)
Conclusion: I attempted to keep the radius of my loop constant while adding more wire turns to it. However, I noticed that the current produced by my set-up decreased as the number of turns increased. Additionally, due to some oversights on my part, there was a significant difference between the readings I obtained from the magnetic field of my coil and the Earth's magnetic field.
