Question

Current I is being carried by and infinite wire passing through origin along the direction i^+j^+ k^. Find magnetic field due to the wire at point (1,0,0)

Answer 1

The magnetic field at the point (1,0,0) is (µ x I) / (4π x (1 / (2)^0.5)) Tesla.

The wire in the above question passes through the line with direction ratios of (1,1,1).

The formula for the magnetic field at a distance d from a wire carrying a current I is:

B = (µ x I) / (4π x d)

The distance between the wire and the point (1,0,0) is given as:

d = (2)^0.5 / 2

d = 1 / (2)^0.5

Hence, the magnetic field at the required point is:

B = (µ x I) / (4π x (1 / (2)^0.5)) Tesla
