Question

A current filament carrying 15A In lhe a direction lies along the entire X axis Find H in rectangular system at point (2,1,0).(7)

Answer 1

Answer:

H = 0.9549 ay - 0.47746 ax  A/m

Explanation:

given data

current = 15A

point coordinate = ( 2 , 1 , 0)

to find out

H in rectangular system

solution

first we find the length at point p

p = √(2²+1²)

p = √5

so we know magnetic field intensity that is

H = current×a  / 2πp   ...............1

here p is point length and find here a

a = az × ( 2ax + ay) / p

a = ( 2ay - ax) / p

so from equation 1

H = 15 ×  ( 2ay - ax)   / 2π√5√5

H = 3 ×  ( 2ay - ax)   / 2π

H = 0.9549 ay - 0.47746 ax  A/m
