Problem-12

Given that A/m in region

(a) and

(b) and in region

*y - x*- 2 â‰¤ 0 where Î¼_{1}= 5Î¼_{0}, calculate(a) and

(b) and in region

*y - x*- 2 â‰¥ 0 where Î¼_{2}= 2 Î¼_{0}Solution

*y - x*â‰¤ 2 or,

*y*â‰¤ (

*x*+ 2) is in the region 1. Let the surface of the plane be described by

*f*(

*x, y*) = (

*y - x*- 2); the unit vector normal to the plane is given as,

(a) Magnetisation vector is,

(b) In the region 1, normal component of the field is,

Tangential component is,

Applying boundary conditions,

And,
