Chapter 31, Problem 36AP

Review. Consider a capacitor with vacuum between its large, closely spaced, oppositely charged parallel plates. (a) Show that the force on one plate can be accounted for by thinking of the electric field between the plates as exerting a “negative pressure” equal to the energy density of the electric field. (b) Consider two infinite plane sheets carrying electric currents in opposite directions with equal linear current densities Js. Calculate the force per area acting on one sheet due to the magnetic field, of magnitude μ0Js/2, created by the other sheet. (c) Calculate the net magnetic field between the sheets and the field outside of the volume between them. (d) Calculate the energy density in the magnetic field between the sheets. (e) Show that the force on one sheet can be accounted for by thinking of the magnetic field between the sheets as exerting a positive pressure equal to its energy density. This result for magnetic pressure applies to all current configurations, not only to sheets of current.

A velocity selector consists of electric and magnetic fields described by the expressions E = E k and B = B ĵ, with B = 10.0 mT. Find the value of E (in kV/m) such that a 840 eV electron moving in the negative x-direction is undeflected. kV/m (b) What If? For the value of E found in part (a), what would the kinetic energy of a proton have to be (in MeV) for it to move undeflected in the negative x-direction? MeV A cyclotron designed to accelerate protons has a magnetic field of magnitude 0.640 T over a region of radius 1.80 m. (a) What is the cyclotron frequency? rad/s (b) What is the maximum speed acquired by the protons? m/s
An electron with kinetic energy 2.5 keV moving along the positive direction of an x axis enters a region in which a uniform electric field of magnitude 10 kV/m is in the negative direction of the y axis. A uniform magnetic field is to be set up to keep the electron moving along the x axis, and the direction of is to be chosen to minimize the required magnitude of . In unit-vector notation, what should be set up?
Suppose a conducting rod (mass m, resistance R) rests on two frictionless and resistanceless parallel rails a distance l apart in a uniform magnetic field B (⊥ to the rails and to the rod) as in the figure. At t = 0 the rod is at rest and a source of emf is connected to the points a and b. Find a formula for the net electric field in the moving rod as a function of time for the case, when the source puts out a constant current I. Find a formula for the net electric field in the moving rod as a function of time for the case when the source puts out a constant emf E0.
