iPad 9:24 AM webassign.net 2 /4 points SerPSET9 30.P031 My Notes Ask Your Teacher The figure below is a cross-sectional view of a coaxial cable. The center conductor is surrounded by a rubber layer, an outer conductor, and another rubber layer in a particular application, the current in the inner conductor is 11 = 1.04 A out of the page and the current in the outer conductor is I2-3.20 A into the page. Assuming the distance d- 1.00 mm, answer the following. (a) Determine the magnitude and direction of the magnetic field at point a. magnitude (No Response) HT direction (No R (b) Determine the magnitude and direction of the magnetic field at point b. magnitude (No Response) HT direction (No Re Need Help?Read ItWatch t 3. -14 points SerPSET9 31.P.003. My Notes Ask Your Teacher

Explanation / Answer

a)

Magnetic field at point a is

B=uoI1/2pia = (4pi*10-7)*1.04/2pi*(1*10-3)

B=208 uT

DIrection is Pointing upwards

b)

Magnetic field at point b is

B=uo(I2-I1)/2pid =(4pi*10-7)(3.2-1.04)/2pi*(3*10-3)

B=144 uT

Direction is pointing downwards
