I could really use some help on some questions! The problem is as follows: A thine wire of length L carries a current I and is positional on top of the x-axis( see picture attached for clarification). The left of the wire lies on the origin. a) What direction is the B-field at point P? b) Determine the magnitude of the B-field at point P. (answer must be written in terms of L, I and a) c) Check the answer from part A by taking the limit L--> ∞ and comparing it to the magnetic field of an infinite straight wire, B=µ0I/2πr. The picture of the wire is attached below for visual. I appreciate the help!
