A cylindrical conductor with a circular cross section has a radius a and a resistivity r and carries a constant current I.
(a) What are the magnitude and direction of the electric-field vector E→ at a point just inside the wire at a distance a from the axis?
(b) What are the magnitude and direction of the magnetic-field vector B→ at the same point? (
c) What are the magnitude and direction of the Poynting vector S→ at the same point? (The direction of S→ is the direction in which electromagnetic energy flows into or out of the conductor.)
(d) Use the result in part (c) to find the rate of flow of energy into the volume occupied by a length l of the conductor. (Hint: Integrate S→ over the surface of this volume.) Compare your result to the rate of generation of thermal energy in the same volume. Discuss why the energy dissipated in a current-carrying conductor, due to its resistance, can be thought of as entering through the cylindrical sides of the conductor

- CASE STUDY In Example 34.6 (page 1111), we imagined equipping 1950DA, an asteroid on a collision course with the Earth, with a solar sail in hopes of ejecting it from the solar system. We found that the enormous size required for the solar sail makes the plan impossible at this time. Of course, there is no need to eject such an object from the solar system: we only need to change the orbit. A much more pressing problem is Apophis, a 300-m asteroid that may be on a collision course with the Earth and is due to come by on April 13, 2029. It is unlikely to hit the Earth on that pass, but it will return again in 2036. If Apophis passes through a 600-m keyhole on its 2029 pass, it is expected to hit the Earth in 2036. causing great damage. There are plans to deflect Apophis when it comes by in 2029. For example, we could hit it with a 10- to 150-kg impactor accelerated by a solar sail. The impactor is launched from the Earth to start orbiting the Sun in the same direction as the Earth and Apophis. The idea is to use a solar sail to accelerate the impactor so that it reverses direction and collides head-on with Apophis at 8090 km/s and thereby keeps Apophis out of the keyhole. Consider the momentum in the impactors orbit (Fig. P34.75) when the solar sail makes an angle of = 60 with the tangent to its orbit. Current solar sails may be about 40 m on a side, but the hope is to construct some that are about 160 m on a side. Estimate the impactors tangential acceleration when it is about 1 AU from the Sun. Keep in mind that the sail is neither a perfect absorber nor a perfect reflector, and a heavier impactor would presumably be equipped with a larger sail. Dont be surprised by what may seem like a very small acceleration.

- A cylindrical region contains a uniform electric field that is parallel to the axis and is changing with time. If r is the distance from the cylinder axis, how does the magnitude of the magnetic field outside the region depend on r?arrow_forwardAccording to Ampere Maxwell's law, if the electric flux density changes with time, a magnetic field will appear there. As shown in the figure, there is a parallel plate condenser consisting of circular pole plates of radius a connected to an infinitely long straight current. When a steady-state current I flows into it, find the magnitude B of the magnetic flux density at a position of radius r from the center of the capacitor. However, the following assumptions are made. (1) The electric field between the poles is uniform and orthogonal to the poles. (2) Due to the symmetry of the system, the magnetic field is circumferential and the magnitude of the field at r from the center is constant.arrow_forwardEe = 130 N/C is the known electric field just above the Earth's surface.
