Magnetic Flux and Pole Definition

AI Thread Summary
Magnetic field lines consistently emerge from north poles and enter south poles, reflecting the fundamental nature of magnetic polarity. This behavior is linked to the concept of polarities, where north is analogous to positive and south to negative. A surface without a magnetic field is not classified as a pole, while a surface with an outward magnetic field indicates a north pole, characterized by positive magnetic flux. Conversely, a surface with an inward magnetic field is identified as a south pole, associated with negative magnetic flux. Understanding these definitions clarifies the nature of magnetic poles and their respective flux characteristics.

The magnetic field lines emerge from the north poles to south poles.Why its always true this event? i expect your answers please... :confused:
 
Physics news on Phys.org
i think it mite b a law of polarities? north go to south@_@ like positive go to negative electrons
 
If there's NO magnetic field piercing a surface (inward or outward),
then it is not a pole at all.

If Magnetic field comes outward through some surface,
we could call that surface a North pole ... (or it is NEAR a North pole).

Most precisely, that surface area has "positive magnetic flux" outward.

The opposite is for magnetic field piercing INto a surface ...
call it a South Pole, or surrface Area with negative magnetic flux.

As a definition ... why does this bother 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...
