Current-Carrying WireNeutral FrameSymmetrical FrameLorentz ForceDrift VelocityIt is commonly assumed that a wire conducting an electric current is neutral in the laboratory frame of reference (the rest frame of the lattice of positive ions). Some authors consider that the wire is neutral only in a...
In this paper, we discuss the Lorentz transformation between different frames of reference in the context of the special theory of relativity for a current-carrying conducting wire and a probe charge in motion with respect to the wire. A simple derivation of the Lorentz force in the laboratory ...
Consider the current-carrying wire shown in the figure. The current creates a magnetic field at the pointP,which is the center of the arc segment of the wire. Ifθ=40.0°,the radius of the arc is0.400m,and the current is4.00A,w...
