PHY 91880 Midterm 3 Exam
An infinitely long straight wire carrying a current I1 = 37 A is partially surrounded by a loop as in figure. The loop has a length L = 31.5 cm, a radius R = 11.1 cm, and carries a current I2 = 29.7 A. The axis of the loop coincides with the wire. R L I1 I 2 Calculate the force exerted on the loop. 1. 311.146 2. 1247.4 3. 593.321 4. 566.24 5. 1691.62 6. 261.6 7. 509.09 8. 274.081 9. 1129.34 10. 3132.88 Correct answer: 1247.4 μN. Explanation: Let : I1 = 37 A, I2 = 29.7 A, L = 31.5 cm = 0.315 m, and R = 11.1 cm = 0.111 m. The central wire creates field B~ = μ0 I1 2 π R counterclockwise
