Question

same current I is flowing in three infinitely long wire is along positive x,y,z directions the magnetic field at a point (0,0,-a) would be​

Answer 1

Answer:

Point (0,0,−a) lies on x-axis, therefore magnetic field due to

current along z-axis is zero and due to rest two infinitely long wires is

μ0/2πa

Magnetic field due to current I in the x-direction is along y-direction.

Magnetic field due to current I in the ydirection is along -ve x-direction.

Therefore,

B_total = μ0/2πa(j-i)

Answer 2

Answer:

hey champ get prepared well for ur exams I too neet aspirant

all the best for the days to come
