Force between parallel conductors

Click For Summary

Homework Help Overview

The discussion revolves around the force of attraction between parallel currents, particularly in the context of its applications and relevance in practical scenarios. Participants explore the significance of this force in defining an ampere and its implications in various technologies.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants question the practical applications of the force between parallel conductors, with some suggesting that it may be more historical or educational than applicable. Others raise the idea of preventing this force in certain contexts, such as in eddy currents.

Discussion Status

The discussion is ongoing, with various perspectives being shared. Some participants acknowledge the limited practical application of the force, while others suggest that it may still have relevance in specific contexts. There is no clear consensus, but several participants provide insights and references to related concepts.

Contextual Notes

Participants note that the force between parallel currents is relatively small, which raises questions about its significance in real-world applications. The discussion also touches on the educational nature of the topic and its historical context in physics.

I have read recently about force of attraction between parallel currents and was wondering that as the force of attraction is quite small when defining an ampere... so are there any of its applications...? :shy:

Electromagnets, motors, etc.
 
actually these are applications of one powerful magnetic field and one magnetic dipole.
I don't know any application of force between two wires, i think it is completely educational and a bit historical.
 
yeah.. you are right about electromagnets and motors.. but there must be some some application of this force being used.. or better, some application to prevent this force between parallel conductors... for example..in eddy currents where to prevent the loss of energy due to these currents we use laminations of metal separated by an insulating material
 
actually, i think it did its time, the very first professional experiment that lead people to believe existence of magnetic force so magnetic field,(the experiment of Ampere's about that force). It is too small to be applied and so small that it is never a problem like eddy currents.
and besides i don't think it can be thought separately, after all it is a force that is by a magnetic field and a current, if you think so, motors are also an application of it, magnetic field is there is produced by nothing but a lot of currents we can think it as a strong current, but i thought you ask spesifically the equation F=I1I2(mu)/2(pi)r so i was against gneill.
 
yes..i asked specifically about attraction between parallel currents..
i know the force is too small, but i just wanted to know...
yeah i agree with you.. it did its time and cannot be applied or be a problem...

thanks gneill and sigmaro for your help..:)
 
the textbook section on the force between two current conductors is probably just an extension of the magnetic force on a charge with the intention of being more of a study exercise than application oriented.
 
ya there r quite a lot of applications of these particularly in most of the electronic gadgets u see arnd urself...
