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...

1.) Consider a very long, straight wire of uniform positive charge density. In the space below, describe the electric field of the wire. In particular, what direction does it point? Does its strength depend on position? If so, how? Note any symmetries of interest. 2.) Use the understanding of electric fields you developed above to deduce the electric field at the center of a circular loop of wire (radius R) with the same positive uniform charge density. Specifically, is it:...

4. (25 points) A hollow conducting pipe has an inner radius of 2a/5 and an outer radius of a. The cross section is as shown below. It carries a current of magnitude Iwith uniform current density within the conductor material. Using Ampere's Law, find the magnetic field magnitude in each region as a function of radius (in the cavity contained within the pipe, within the pipe itself, and outside the pipe). Sketch a graph of the magnetic field magnitude as...
