Nonstationary magnetic field problems in a moving conductor are of interest in connection with obtaining pulsed magnetic fields by magnetic cumulation [1], The field penetrates into the conductor as a result of the growth of the skin layer and is carried along with the conductor. The first ...
Experiments were performed to further understand the forces acting on magnets moving near the edge of a conducting strip and to produce a data set for the validation of analysis methods. Mapping the magnetic field gives information about the eddy currents induced in the conductor which agrees with...
I THINK there is, in Another Place, possibly some misunderstanding concerning the inertia of a moving charged conductor due to the magnetic energy set up by its motion. It depends upon the distribution of the electrification, and may vary from a minimum up to infinity. No question of distortio...
This question comes from the equation E = vB (moving conductor in a magnetic field -- E = electric intensity, v= speed of the conductor's movement, and B = magnetic field strength). Say B is constant, so the only thing we have to rely on to vary the electric intensity in the condu...
Work done by a moving conductor in a magnetic field Homework Statement Show that there is a force of 0.1N on a conductor of length 100mm carrying a current of 10A at right angles to a flux density of 0.1T. Show that 0.1J of work is done if the conductor is displaced by 100mm at ...
Calculate the magnetic force on a current-carrying conductor. Because charges ordinarily cannot escape a conductor, the magnetic force on charges moving in a conductor is transmitted to the conductor itself. Figure 1. The magnetic field exerts a force on a current-carrying wire in a direction ...
Jim has taught undergraduate engineering courses and has a master's degree in mechanical engineering. Cite this lesson Electromagnetic induction is the production of electromotive force by moving a magnetic field across an electric conductor. Learn more about mutual inductance, its applications, and tran...
One obtains the corresponding magnetic intensity vector by using Eq. (1.1b). While the wave is attenuated as it propagates along the z-direction, it is in the nature of a homogeneous wave in that the surfaces of constant amplitude coincide with those of constant real phase, both sets of ...
