Question
The two wires shown in the figure below are separated by d = 12.3 cm and carry currents of 1 : 5.05 A in opposite directions. P2 2d (a) Find the magnitude and direction of the net magnetic field at a point midway between the wires magnitude direction Select UT (b) Find the magnitude and direction of the net magnetic field at point Ps, 12.3 cm to the right of the wire on the right. magnitude l direction Se AT -Select- (c) Find the magnitude and direction of the net magnetic field at point P, 2d -24.6 cm to the left of the wire on the left magnitude direction IT Select Need Help? Lend.Explanation / Answer
a) B = mu0 I / 2 pi r + mu0 I / 2 pi r
= 2 * mu0 I / 2 pi r = (2 * 4 pi * 10-7 * 5.05) / (2 pi * 0.0615)
= 3.28 * 10-5 T = 32.8 muT

b) B = mu0 I / 2 pi d - mu0 I / 2 pi (2 d)
= mu0 I / 2 pi r = [( 4 pi * 10-7 * 5.05) / (2 pi * 0.123)] - [( 4 pi * 10-7 * 5.05) / (2 pi * 0.246)]
= 4.10 * 10-6 T = 4.1 muT

c) B = mu0 I / 2 pi (2 d) - mu0 I / 2 pi (3 d)
= mu0 I / 2 pi r = [( 4 pi * 10-7 * 5.05) / (2 pi * 0.246)] - [( 4 pi * 10-7 * 5.05) / (2 pi * 0.369)]
= 1.37 * 10-6 T = 1.37 muT
