A long rod, radius R, that has uniform positive charge density p is spun around its central axis with angular velocity w, as shown below, so that the charges follow circular paths centered on the axis. Current is the flow of charge, so we have rings of current of varying radius r. You may want to review the following relationships: Current density J = dI/dA = pv (from chapter 24!) and v=wr (from PHY 204!) This means that the rotating rod of charge is equivalent to a non-uniform current density J = pwr, where the current is circulating around the axis and r is the radial distance from the axis. Note this has the same symmetry as the solenoid (current flowing in circles, field lines straight and parallel to the axis). The difference is that this is like having many nested solenoids, and as we head out from the axis, we see more and more current. R I will walk you through the steps for using Ampere's law to find the magnetic field inside the rod. (a) Draw a diagram of a cross section of…
