Q.60 A surface curent K =100 i A/m flows on the surface z = 0, which separates two media with magnetic permeabilities pi and p2 as shown in the figure. If the magnetic field in the region 1 is B = 4i-6ý+22 mT, then the magnitude of the normal component of B, will be mT. Z>0 4=5x10°H/m B =4-6+2 mT K =100 A/m B =10 x10°H/m Z0
