Question

7.11 A rectangular loop carrying 10 A of current is placed on z = 0 plane as shown in Figure 7.32. Evaluate H at (a) (2,2,0) (b) (4,2,0) (c) (4, 8,0) (d) (0,0,2)

Answer 1

Answer:

Given that Z = 0

H = 1 + 2 + 3 + 4

H = H2

H = 271 +H2+H4

a)

( 2 , 2 , 0 )

H1 (cosa2 – cosa1) ao

  

H1 = ਜੋਰ ਕਰ

  

H:= (2* 147

H = 1 2- 、 104

H

5.2 1. 5 - 5 laz = 1.9642A/m V2 610272 T-

b)

( 4 , 2 , 0 )

At ( 4,2,0)

H = 2(H1 + HA)

10 8 H2 = 47(2) / 20°

H = 10 4 14 = 46(4) V2007

$\bar{H} = \frac{2\sqrt{5}}{\pi } [1+\frac{1}{4}]a_{Z}$

= 1.78$\bar{_{Z}}$ A / m.

c)

( 4 , 8 , 0 )

H = H1 +2H2 + H2

3 = 2- 2

d)

at ( 0 , 0 , 2 )

H-10 | 47(22) - (a + (2)
