pallidin said:IMHO I don't think so, as the straight wire has no loop back connection to each end.
Thus, no current flow, no back emf.
But a copper "ring" would be a different story.
Just my thoughts, could be wrong.

pallidin said:Why are there "charged" particles on the ends of the wire in your scenario? The copper wire has many charged particles but is electrically neutral in your description.
Astronuc said:Well conductors (e.g., metals) have electrons in their atoms. Some of the electrons are quite mobile, i.e., they can readily move if an external force is applied, e.g., through potential difference applied to the conductor, or if the conductor is moved through a magnetic field.
physmath96 said:In this case, a wire segment is moving through a magnetic field. The equation that applies to this case is: emf = vBL, which holds only when v (velocity), B (magnetic field), and L (length) are mutually perpendicular. Looking at the diagram, one can see that the three values are not mutually perpendicular, and thus, no emf will be induced. The wire will not slow down.
Disinterred said:I don't think he was wondering about the emf. I think he wanted to know what force would be applied, if any. In this case, a force will only be applied if v and B are not parallel (qv x B).
Electromagnetic induction is the process of generating an electric current in a conductor by changing the magnetic field around it. This occurs when a conductor is moved through a magnetic field, or when a magnetic field is changed around a stationary conductor.
Electromagnetic induction is based on Faraday's law of induction, which states that a changing magnetic field will induce an electric current in a conductor. This shows the intimate relationship between electricity and magnetism, as they are fundamentally linked through the concept of electromagnetism.
Electromagnetic induction has many practical applications in our daily lives. It is used in generators to produce electricity, in transformers to change the voltage of electric currents, and in devices like electric motors, induction cooktops, and wireless charging systems.
Lenz's law is another important concept in electromagnetic induction. It states that the direction of an induced current will always oppose the change that caused it. This means that when a conductor is moved through a magnetic field, the induced current will create a magnetic field that opposes the original magnetic field.
Understanding electromagnetic induction is crucial in the design of electronic devices. Engineers must consider the effects of electromagnetic induction when designing circuits and components to ensure that unwanted currents or voltage spikes do not occur. They also use electromagnetic induction principles to create devices like inductors and transformers that are essential in many electronic systems.
