Calculating Current Induced in a Moving Loop

AI Thread Summary
To calculate the current induced in a moving loop within a magnetic field, it's essential to understand the relationship between velocity, area, and magnetic flux. The loop's velocity of 50 m/s affects how much of the loop is within the 0.20 T magnetic field, which in turn influences the changing area and magnetic flux over time. The induced electromotive force (E) can be calculated using the formula E = |d magnetic flux/dt|, and the current (I) can be determined with I = E/R, where R is the resistance of the loop at 0.10 ohm. Understanding how to derive the changing length of the loop in the magnetic field is crucial for solving the problem. This approach will help clarify the relationship between the loop's motion and the induced current.

Homework Statement


The loop in the figure is being pushed into the 0.20 T magnetic field at 50 m/s. The resistance of the loop is 0.10 ohm.


Homework Equations


I=E/R
E=|dmagnetic flux/dt|


The Attempt at a Solution


I don't know how to even start this problem all the examples give more information. I don't see what the velocity does for this problem or how to figure out the area since all they give is the width. Some help or how to approach would be much appriciated.

I can't see the picture yet, but I think I offer some tips.
The velocity is important as it tells you how much of the loop (and therefore area) is in the magnetic field. You get your "length" from that (it will be changing). You need that for the flux, which will be changing based on how much of the loop is in the field.
 
What do you have to find?
 
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...
