Why Does Fleming's Right Hand Rule Give an Upward Force on the Wire?

Click For Summary

Homework Help Overview

The discussion revolves around the application of Fleming's Right Hand Rule in determining the direction of the force on a current-carrying wire placed between magnets. Participants are exploring the correct usage of this rule in the context of magnetic forces.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to apply Fleming's Right Hand Rule but questions the outcome, indicating a discrepancy with expected results. Another participant suggests using Fleming's Left Hand Rule instead, prompting further exploration of the rules' applications.

Discussion Status

The discussion is ongoing, with participants providing different perspectives on the application of the hand rules. Some guidance has been offered regarding the potential need to switch from the Right Hand Rule to the Left Hand Rule, but no consensus has been reached.

Contextual Notes

Participants are working under the assumption that the original poster's application of the Right Hand Rule may not align with the expected answer, leading to a discussion about the correct approach to the problem.

Fleming's hand rules

The Attempt at a Solution


I used the Flemings right hand rule but that gives me that the force on wire is upwards. But the answer is otherwise. Thanks for your help!
