show calculations plz
Two very long parallel wires carry currents in the positive x direction. One wire (current = 15 A) is coincident with the x axis. The other wire (current = 50 A) passes through the point (0,4.0 mm,0). What is the magnitude of the magnetic field at the point (0,0,3.0 mm)? 10. Each of two parallel wires separated by 8.0 mm carries a 20-A current. These two currents are oppositely directed. Determine the magnitude of the magnetic field at a point that is 5.0 mm from each of the wires.Explanation / Answer
9)B = u0sqrt(225/9+2500/16)/2pi
= 2*10^-7*13.463*10^-3
= 2.69 *10^-3 T
~2.7mT
10) cos(theta) = 4/5
B = u0(20+20)cos(theta)/2pi5
= 2*10^-7*40*10^-3*4/5*5
= 1.3mT
