A long, straight wire lies along the z-axis and carries a 4.20-A current in the +z-direction. Find the magnetic field (magnitude and direction) produced at the following points by a 0.500 mm segment of the wire centered at the origin.

Complete question:

A long, straight wire lies along the z-axis and carries a 4.00-A current in the +z-direction. Find the magnetic field (magnitude and direction) produced at the following points by a 0.500-mm segment of the wire centered at the origin:

(a) x = 2.00 m, y = 0, z = 0;

(b) x = 0, y = 2.00 m, z = 0;

(c) x = 2.00 m, y = 2.00 m, z = 0; (d) x = 0, y = 0, z = 2.00 m.

a) ;

b) ;

c) ;

d) 0

Explanation:

Given

I = 4.20A

P = 0.500mm

a) r= (2.00m) i

∆;

;

b) r = (2.00m) j

∆;

;

c) r = (2.00m) (i+j)

;

∆;

;

d) r = (2.00m) k

∆;

B = 0

answer: good job it's all correct !
