Net Magnetic Force on Rect. Current Loop

Click For Summary

Homework Help Overview

The problem involves a rectangular current loop situated near a long, straight wire carrying a current. The objective is to determine the magnitude of the net magnetic force acting on the loop, given specific dimensions and currents.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the application of the formula for magnetic force and consider the configuration of the wire relative to the loop. There is a focus on calculating the force on each side of the rectangle and recognizing the cancellation of forces on the shorter sides.

Discussion Status

Some guidance has been provided regarding the use of the correct formula and the approach to finding the net force by considering the contributions from each side of the rectangle. Participants are exploring the implications of the wire's position and the need for a visual representation.

Contextual Notes

There is a mention of a missing drawing that could clarify the setup, which may influence the interpretation of the problem.

A rectangular current loop (L=0.40 m and W=0.19 m) is located near a long, straight wire (d=0.10) that carries a current of 10 A (see the drawing). The current in the loop is 20 A. The Determine the magnitude of the net magnetic force that acts on the loop.

i was chugging my B from the wire into f=IlB

We don't have the drawing (couldn't u attach it ?).It would make much difference how the straight conducting wire would be located wrt the rectangle...

oops, sorry!

You are using the correct formula. Find the force on each side of the rectangle and find the net force. You will see that the forces on the shorter sides cancels each other. So you have to consider the forces on only the longer sides of the rectangle.
