- A current I flows around a wire bent into the shape of a square of side a. Finding the electric field for a square wire with uniform charge.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…Consider a right-hand Cartesian coordinate system as shown in Figure 14.3 on page 701. We have a wire along the x-axis carrying 12 A in the positive x direction and a constant flux density of 0.3 T directed in the positive z direction. a. Determine the force and its direction on a 0.2 m length of the wire. b. Repeat if the field is directed in the positive x direction.

- Parallel conducting plates create nearly uniform fields that are used to accelerate and direct beams of electrons. Typically we would free the electrons from a surface by heating it up. One way is to run a current through a wire with resistance. The power dissipated in the wire causes it to increase its temperature to the point that it can radiate that power away, mostly carried off as light. The hot electrons escape the potential barrier at the surface and are "free" to use. Consider a source of electrons that is small, like a tiny hot filament. The electrons are freed from the surface but the positive charge they leave behind holds them in a cloud near the filament. Now we add another plate at voltage VV some distance dd away. We put a little hole in that plate to enable the electrons to zip on through. The experiment looks something like this. While they seem antiquated, the concept is still useful. It is the basis of modern X-ray tubes, and until only a few years ago all…A simple and common technique for accelerating electrons is shown in the figure, which depicts a uniform electric field between two plates. Electrons are released, usually from a hot filament, near the negative plate, and there is a small hole in the positive plate that allows the electrons to pass through.Randomized VariablesE = 2.7 × 104 N/C Calculate the horizontal component of the electron's acceleration if the field strength is 2.7 × 104 N/C.
