AI Thread Summary
The discussion focuses on applying PERE'S Law and Faraday's Law of Induction to determine the induced potential difference in various scenarios involving a coil and a bar magnet. The original setup with a 500-turn coil generates an induced voltage of 1.5 volts. Changes proposed include reducing the coil to 250 turns, increasing the speed of the magnet's movement, and using three magnets simultaneously. The participants emphasize the need to apply the correct physics laws to calculate the induced emf for each scenario. The conversation highlights the importance of understanding the relationship between magnetic field changes and induced voltage.

Homework Statement



A bar magnet inserted into a coil of 500 turns produces an induced potential of 1.5 Volts, Determine the potential difference induced when each of the following changes are made

a) a 250 turn coil is used
b) the bar magent is moved twice as fast
c) Three identical magnets are inserted at once, side by side
d) All three of the aboce changes occur together

Perhaps you could start by stating the applicable law of physics (the relationship between emf generated and the time dependent magnetic field). Hint: it is not Lenz' 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...
