Question

Two very long current carrying conductors lie in the same plane as shown. Current I_1 = 2.50 A runs west to east and current I_2 = 5.00 A runs south to north. Choose the origin (x = 0, y = 0, z = 0) as the point where the wires cross. Determine the magnitude and direction of the net magnetic field at the point (x = 5.00 cm, y =0.cm, 2 = 0). Determine the magnitude and direction of the net magnetic field at the point (x = -3.00 cm, y =cm, 2 = 0). Determine the magnitude and direction of the net magnetic field at the point (x = 0, y = 0, 2 =cm).

Explanation / Answer

here B1 will be upward and B2 will be upward as well
Bnet = B1+B2
=miuo*[I1/r1 + i2/r2] *1/2pi
= (1.2566*10^-6)*[2.5/0.02 + 5/0.03]*1/2pi
= (1.2566*10^-6)*291.7/2pi
= 5.83*10^-5 T
in positive z direction
