Question

The two wires shown in the figure below are separated by d = 10.6 cm and carry currents of I = 4.50 A in opposite directions. (a) Find the magnitude and direction of the net magnetic field at a point midway between the wires. magnitude 33.9 mu T direction into the page (b) Find the magnitude and direction of the net magnetic field at point P_1, 10.6 cm to the right of the wire on the right. magnitude 4.25 mu T direction out of the page (c) Find the magnitude and direction of the net magnetic field at point P_2, 2d = 21.2 cm to the left of the wire on the left. magnitude 0.166 Your response differs from the correct answer by more than 10%. Double check your calculations. mu T direction out of the page

Explanation / Answer

c.) magnetic field due to long wire = mu I/2*pi*d

magnetic field due to both wire at poin P2 = (mu*I/2pi)(1/2d - 1/3d)

B = (4pi*10^-7 *4.5 / 2*pi)(1/2*0.106 - 1/3*0.106)

B = 1.415 uT

direction is out of the page
