torque

[figs]

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

[Doc Al]

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

[Doc Al]

how am i to fig out N? t=NIABsin90
A 0.477 m length of wire is formed into a single-turn
N is the number of turns.

[figs]

that's wut i thought
t=(1)(13.5A)(0.014m2)(0.124)(sin90)
t=0.023 N*m

i did something wrong somewhere
