B Field Due To a Hairpin
A long hairpin is formed by bending an infinitely long wire, as shown. If a current of 2.8 A is set up in the wire, what is the magnitude of the magnetic field at the point a? Assume R = 11 cm.
Homework Answers
let the current flow in an anti-clockwise direction,
magnetic field due to semi-circular wire = 1/2(μI/2r). (in a direction perpendicular to the plane of ur screen)
magnetic field due to upper stright wire(half infinite wire) = 1/2(μI/2πr),(in the same direction)
magnetic field due to lower stright wire(half infinite wire) = 1/2(μI/2πr). (in the same direction)
as three are in same direction add those ans = μI/4r+μI/2πr =
=4π*10-7*2.8[2/(4*π*0.11) + 1/(4*0.11) ]
=4*π*10-7*2.8*2.272
=8.141 x10-6 T

In the figure below, a current i = 10 A is set up in a long hairpin conductor formed by bending a wire into a semicircle of radius R = 5.0 mm. Point b is midway between the straight sections and so distant from the semicircle that each section can be approximated as being an infinite wire. What are the (a) magnitude and (b) direction (into or out of the page) of B at point a and the (c) magnitude...

An infinitely long, straight, cylindrical wire of radius R carries a uniform current density J. Using symmetry and Ampere's law, find the magnitude and direction of the magnetic field at a point inside the wire. For the purposes of this problem, use a cylindrical coordinate system with the current in the +z-direction, as shown coming out of the screen in the top illustration. The radial r-coordinate of each point is the distance to the central axis of the wire, and...
