Torque on a loop of wire carrying a current

AI Thread Summary
To calculate the maximum torque on a square loop of wire carrying a current, the area of the loop is needed, which can be derived from the wire's length. The wire's total length is 0.477 m, allowing the determination of the side length of the square. The torque formula used is t = NIABsin(θ), where N is the number of turns, I is the current, A is the area, and B is the magnetic field strength. In this case, with one turn (N=1), the calculated torque is 0.023 N*m, indicating a possible error in the area calculation. Accurate area measurement is crucial for correct torque computation.

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

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
