Electromagnetic induction inside a field with a contraint

Click For Summary

Homework Help Overview

The discussion revolves around electromagnetic induction and the conditions under which current can be generated in a closed loop situated in a magnetic field created by fixed permanent magnets. Participants explore the implications of the magnetic field being a vector and the potential for altering the field by repositioning magnets.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants question the conditions necessary for generating current, particularly focusing on the fixed nature of the magnets and the implications of having a movable magnet. There is a discussion about the relationship between magnetic field vectors and magnetic flux.

Discussion Status

The conversation is ongoing, with participants clarifying misunderstandings about the setup of the magnets and the conditions for inducing current. Some guidance has been provided regarding the necessity of movement to generate current, but there is no explicit consensus on the original poster's understanding of the concept.

Contextual Notes

Participants are grappling with the constraints of the problem, specifically the fixed position of the magnets and how that affects the ability to generate current in the loop.

1. A closed loop is held stationary in the magnetic field between the north and south poles of two permanent magnets held fixed. Can we hope to generate current in the loop by using very strong magnets?


well, my doubt is: as magnetic field is a vector and since we have two pairs [one movable pair] we can alter the net field, right? [by holding in different positions] and thereby change the flux?
anyway the answer is no and I believe I didn't get the concept right!

It says both magnets are fixed. How do you jump to the conclusion that one of them is moveable?

oh, sorry I meant to ask if one was movable can we make a change.

Yes, if one or both were moveable then you could get current in the loop.
But they're not, are they.

you are rude, but thanks for the help
