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!

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
