A long straight very thin wire on the y-axis carries a 10-A current in the positive y-direction. Acircular loop 0.50 m in radius, also of very thin wire and lying in the yz-plane, carries a 9.0-Acurrent, as shown. Point P is on the positive x-axis, at a distance of 0.50 m from the center of theloop. What is the magnetic field vector at point P due to these two currents?

In the figure below, a long circular pipe with outside radius R=2.18 cm carries a (uniformly distributed) current i = 9.57 mA into the page.

A magnetic field of strength 0.29 T is directed perpendicular to a plane circular loop of wire of radius 29 cm. Find the magnetic flux through the area enclosed by this loop.
Suppose that the current density carried by an infinite cylindrical wire is not uniform but in fact varies as Jz(u) = J0 * [1 - (u2 / R2)], where J0 is the value of the current density at the wire's center, R is the radius of the wire, and u is distance from the axis of the wire. Assuming that the magnetic field is circular, compute the wire's magnetic field both inside and outside the wire. (Ampere's law makes even nonuniform current densities manageable.) (Hint: The answer is BФ = 0.25 * μ0 * J0 * R on surface at u = R.)

An infinite length line carries current I in the +az direction on the z-axis, and this is surrounded by an infinite length cylindrical shell (centered about the z-axis) of radius a carrying the return current I in the -az direction as a surface current. Find expressions for the magnetic field intensity everywhere. If the current is 1.0 A and the radius a is 2.0 cm, plot the magnitude of H versus radial distance from the z-axis from 0.1 cm to 4 cm.
