Does Magnetic Force on a Wire Loop Affect Flux Change in a Solenoid?

AI Thread Summary
The discussion centers on the relationship between the magnetic force on a wire loop and the change in net magnetic flux through the loop, particularly in the context of a solenoid with varying current. The user has calculated the induced electromotive force (emf) and current but struggles to connect the magnetic force on the loop to the flux change. They seek guidance on how to derive an equation for magnetic field (B) in terms of force to clarify this relationship. The mention of Lenz's Law suggests a focus on the direction of induced currents and their effects on flux. Understanding these concepts is crucial for solving the problem effectively.

Homework Statement


Is the magnetic force on the wire loop in a direction tha would tend to increase or decrease the change in net flux through he wire loop.(This situation has a solenoid with current running through it right next to it, the current is being turned on and off.)


Homework Equations



flux=integral of B dot dA
induced emf=-N time the derivative of flux with respect to time

The Attempt at a Solution


I have my force vectors, and my magnetic moments, and Isee they are in the same direction, and I have found the induced emf, and current, but I don't see the relationship between the magnetic force on the loop and the change in flux. Could someone help point me out in the right direction here.

I feel like the best thing I could do would be to find an equation to plug in for B that is in terms of force but I have no such equation.

Thank you.

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'

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...
