Magnitude of the maximum torque on a current loop.

AI Thread Summary
The discussion centers on calculating the maximum torque on a current loop with a specified area, current, and magnetic field. The user initially calculates the force but receives an incorrect answer due to a mistake in converting the area from cm² to m². The correct area conversion is crucial for accurate torque calculation. The community member points out the error, emphasizing the importance of attention to detail in unit conversions. The user acknowledges the mistake and expresses gratitude for the assistance.

Homework Statement


A current loop in a motor has an area of 0.62 cm^2. It carries a 207 mA current in a uniform field of 1.43 T. What is the magnitude of the maximum torque on the current loop?

A = .0062 m^2
I = .207 A
B = 1.43 T


Homework Equations


F=(IA)Bsin(theta)


The Attempt at a Solution


F = (.207)(.0062)(1.43)sin90 = .001835262N*m

I am not sure what I am doing wrong. I have finished all the problems assigned to me but the computer tells me this answer is wrong. Any help would be appreciated!

Hi shaizen, welcome to PF.
Your conversion of area from cm^2 to m^2 is wrong. Check it.
 
Thanks a lot! I knew it was something simple I wasn't paying attention to.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
