Electricity & Magnetic Fields - What do they Resemble?

AI Thread Summary
When electricity flows through a coil of wire, it generates a magnetic field that resembles that of a bar magnet. This magnetic field exhibits characteristics similar to a bar magnet, including the presence of north and south poles that can attract and repel. While the magnetic field around a straight wire and a circular magnetic disc are also mentioned, the discussion emphasizes the resemblance to a bar magnet. The distinction between resemblance and behavior is noted, clarifying that the question focuses on appearance rather than functionality. Ultimately, the consensus is that the magnetic field created by the coil closely resembles that of a bar magnet.

When electricity flows through a coil of wire, what does the resultant magnetic field resemble?

a the magnetic field of a bar magnet
b the magnetic field of a horseshoe magnet
c the magnetic field around a straight wire
d the magnetic field around a circular magnetic disc.

ok so i know that it creates a circular like magnetic field like that of a bar magnet, but I am not sure if it acts like a bar magnet also having north and south poles which attract and repel, and c doesn't really give me much to think on, so I am not sure whether it would be a, b, or d.

The question just asks what the field resembles and not what it acts like. You know it resembles that of a bar magnet.
 
o ok 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...
