Current Direction Electromagnetic Electromagnetic induction Induced Induced current Induction

AI Thread Summary

To determine the direction of induced current in a loop of wire, apply Lenz's Law, which states that the induced current will flow in a direction that opposes the change in magnetic flux. If the magnetic field increases, the induced current will generate a magnetic field in the opposite direction to counteract the change. Conversely, if the magnetic field decreases, the induced current will flow to maintain the existing magnetic field. Understanding the relationship between magnetic flux changes and induced current direction is crucial for solving related homework problems. Mastering these concepts will enhance comprehension of electromagnetic induction principles.

the direction is such that it opposes the change in magnetic flux ... like if field increase ... it will set up current to oppose it ...
use lenz's law

Thread 'Errors and significant figures'

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
