Unformatted text preview: assuming the y direction is parallel with earth’s gravitational field. 2. The gravitational torque is 0.0018 Nm. The scale reading is 7.25 grams. 3. The magnetic force produced by the small coil. 4. 5. The magnetic force produces a torque as show by countering the gravitational force that produce torque. Results: I(amps) Weight(g) τg τm 0.9 0.06 0.0000153 0.0035 1.62 0.14 0.0000357 0.0063 2.93 0.24 0.0000612 0.0113 3.94 0.31 0.00007905 0.0153 5.52 0.47 0.0001985 0.0214 Conclusion: Using several weights and different amperages, we were able to determine a magnetic force can create a substantial torque to counter earth’s gravitational field and torque. Some sources of error may include vibration of the table and improper calibration of the scale due to touching the magnetic arm with the small coil....
