Homogeneization of physic formula of electromagnetic field and velocity

AI Thread Summary
The discussion centers on a confusion regarding the units in electromagnetic field equations, particularly the relationship between electric potential (\vec A) and velocity (\vec v). The original poster notes that their calculations yield units of volts per velocity, which raises questions about the validity of this unit. They also explore the units of the magnetic field, finding discrepancies when using different approaches, such as \vec v X \nabla X \vec A versus using Tesla multiplied by velocity. Clarifications indicate that the poster mistakenly equated the units of \vec A with velocity, as \vec A actually has units of Tesla·m, not m/s. The conversation emphasizes the importance of correctly understanding the dimensional analysis in electromagnetic equations.

https://www.youtube.com/watch?v= I have a little problem with a formula, that I think it's not ok. It gives to me the result of units of electric potential (\vec A) and velocity \vec v. The result seems to be volts per velocity, and I don't know it there exists this unit, or is a mistake.

In other hand, when i try to develope the units of the magnetic field, if i use \vec v X \nabla X \vec A it gives to me units of diference of potential per unit of time:

\frac {[L]}{[T} \frac {1}{[L]} \frac {[L]}{[T]} = <u>/[T]</u>

and using tesla x velocity, it gives different result:
\frac {[L][M]}{[T]^3 <i>} </i>

I don't know what I'm not doing correctly. Could you give me a little help?

Thanks.

Maybe the problem is that I must utilize power ecuations... like UI and FV. The problem now is that I have an equation that has UIFV, with dimensions of power^2...

I don't understand what you did here. Okay, I see that
v → L/T
del operator → 1/L
but why do you say
A → L/T ?​
A has units of Tesla·m, not m/s as you are implying.

and using tesla x velocity, it gives different result:
\frac {[L][M]}{[T]^3 <i>} </i>

This is correct.

See above; it looks like you incorrectly equated A with a velocity.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
