Assume that I = 6.0A . (Figure 1) What is the magnetic field strength at point a? What is the magnetic field strength at point b? What is the magnetic field direction at point b? What is the magnetic field strength at point c? What is the magnetic field direction at point c?

Explanation / Answer

At point a-

due to wire1-

B1=0i/2?d=6*10-5T(outward)

Due to wire2-

B2=0i/2?d=2*10-5T(inward)

Hence Bnet=B1+B2=4*10-5T (outward)

At point b-

due to wire1-

B1=0i/2?d=6*10-5T(inward)

Due to wire2-

B2=0i/2?d=6*10-5T(inward)

Hence Bnet=B1+B2=12*10-5T (outward)

At point c-

due to wire1-

B1=0i/2?d=2*10-5T(inward)

Due to wire2-

B2=0i/2?d=6*10-5T(outward)

Hence Bnet=B1+B2=4*10-5T (outward)
