Consider an infinitely long, straight conducting wire carrying a constant and uniform free current density jf = jf k^ along the axis of the wire, which coincides with the z axis. the wire has a circular cross section of radius a. the wire is made of a diamagnetic conducting material of permeability î¼.
a) by taking advantage of the symmetry of the problem and of maxwell's equations, find the field h inside the wire.
b) find the expression for the magnetization m in the material.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
