Two movable wires in Magnetic Field

Click For Summary

Homework Help Overview

The discussion revolves around the behavior of two movable wires in a magnetic field, focusing on the induced electromotive force (emf) and the forces acting on the wires due to their motion and the magnetic field. Participants explore the dynamics of the system, including the effects of induced currents and the interaction between the wires.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants discuss the initial conditions of the wires, the forces acting on them, and the implications of induced emf. There are questions about the neglect of forces between the wires compared to the external magnetic field and the conditions under which momentum conservation applies. Some participants express uncertainty about the final velocities of the wires and the nature of their interaction.

Discussion Status

The discussion is active, with participants raising various hypotheses about the behavior of the wires and the forces involved. Some guidance has been offered regarding the application of Faraday's Law and the relationship between induced emf and current. Multiple interpretations of the problem are being explored, particularly concerning the motion and interaction of the wires.

Contextual Notes

Participants note the lack of information regarding the distance between the wires and the nature of their interaction, which affects their reasoning about forces and motion. The discussion also touches on the assumption that the wires do not collide, which influences the analysis of their velocities.

I suspect that you are meant to neglect the force of one wire on the other wire compared to the force that each wire experiences from the external B field.

Hi ,

Don't you think even if we do not neglect the force of one wire on the other wire , it would not affect the final speed of the sliders ? The two forces would cancel each other as far as momentum conservation is concerned .

Yes, I think that's right. The momentum would still be conserved and the final velocities of the sliders would still be equal. Nice!
