Question

The current in the wire at y = -6.0 cm is in the -x direction and the current in the wire at y = +6.0 cm is in the +x direction. The current in each wire is 26 A. Find the magnetic field at the following points on the y axis.

(a) y = -3.8 cm 0 Correct: Your answer is correct. mT i + 0 Correct: Your answer is correct. mT j + mT k

(b) y = 0 0 Correct: Your answer is correct. mT i + 0 Correct: Your answer is correct. mT j + Incorrect: Your answer is incorrect. mT k

(c) y = +2.0 cm 0 Correct: Your answer is correct. mT i + 0 Correct: Your answer is correct. mT j + mT k

(d) y = +9.0 cm 0 Correct: Your answer is correct. mT i + 0 Correct: Your answer is correct. mT j + mT k

Explanation / Answer

Since the answer is incorrect for part b) here is the answer for only part b)

b)

Bnet = B1 + B2 ………both along –z direction

Bnet(-z) = 0I1/2r1 + 0I2/2r2 = (0I/2)*(1/r1 + 1/r2) = [(4*10^-7*26)/(2)]*(1/0.06+1/0.6) = 95.33T

Thus Bnet= (0i + 0j -95.33Tk)
