AI Thread Summary
Electromagnets are coils of wire that generate a magnetic field when an electric current passes through them. They are widely used in applications such as electric motors, generators, and magnetic levitation systems to generate electricity and control mechanical movement. During electromagnetism, the interaction between electric currents and magnetic fields occurs, enabling various technologies. Advantages of electromagnets include their ability to be turned on and off and their adjustable strength, while disadvantages include heat generation and reliance on a power source. Future developments may focus on improving efficiency and miniaturization for advanced applications.

What do you think the answers are to these? What do you feel electromagnetism is from your knowledge through research?
 
does it help in creating electricity?
 

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...
