How to prove Fardays' law of electromagnetic induction

AI Thread Summary
To prove that Faraday's law of electromagnetic induction is consistent with the principle of conservation of energy, one must demonstrate how induced electromotive force (EMF) arises from changing magnetic fields. The key is to show that the work done to move a conductor through a magnetic field or to change the magnetic field around a conductor results in energy being converted into electrical energy. This aligns with the conservation of energy, as the energy input equals the energy output in the form of induced current. Additionally, the relationship between the induced EMF and the rate of change of magnetic flux is crucial in this proof. Understanding these principles solidifies the connection between Faraday's law and energy conservation.

I apologize for not being clear enough.The question should instead read as:

"Prove that Faraday's law of electromagnetic induction is consistent with the principle of conservation of energy".
 

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...
