Torque on a loop of wire carrying a current

Click For Summary

Homework Help Overview

The problem involves calculating the maximum torque experienced by a single-turn square loop of wire carrying a current in a magnetic field. The loop's dimensions and the current are provided, but the area of the loop is not directly given.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the need for the area of the loop to calculate torque, with some suggesting that the square's dimensions can be derived from the given wire length. Questions arise regarding the number of turns in the loop and its relevance to the torque calculation.

Discussion Status

Participants are actively exploring the relationship between the wire length, the dimensions of the square loop, and the torque formula. Some guidance has been offered regarding the calculation of the area and the implications of the number of turns, but no consensus has been reached on the correct approach or any errors in calculations.

Contextual Notes

There is a focus on deriving necessary parameters from the given information, and participants are questioning the definitions and assumptions related to the problem setup, particularly regarding the area and the number of turns.

A 0.477 m length of wire is formed into a single-turn, square loop in which there is a current of 13.5 A. The loop is placed in a magnetic field of 0.124 T, as shown in the figure below. What is the maximum torque that the loop can experience?

if i had the area i could figure it out

But you know it's a square and you have its circumference!

YOu can figure out what is the length of the sides of the square from the given information.
 
how am i to fig out N? t=NIABsin90

N is the number of turns.
 
that's wut i thought
t=(1)(13.5A)(0.014m2)(0.124)(sin90)
t=0.023 N*m

i did something wrong somewhere
