Click For Summary
In the discussion about the polarity of a solenoid, it is questioned whether both ends can be South poles under normal conditions. The Clock rule mentioned is not recognized in standard physics, leading to confusion. Participants agree that if both ends are identified as South poles, it raises the question of where the North pole is located. It is clarified that the North pole is typically found along the top portion of the solenoid's core. The conversation emphasizes the importance of understanding magnetic polarity in solenoids.

Homework Statement
I encountered the following question but by using Clock rule, both the ends are coming out to be South poles. Is this possible? If not, then what will be the polarity at both ends?

None

Yes. I don't recall ever hearing of such a Clock rule in physics. I do agree with you that both A and B are South magnetic poles.

Where is the North Pole or Poles? Along the top portion of solenoid's core.
 
If have close pipe system with water inside pressurized at P1= 200 000Pa absolute, density 1000kg/m3, wider pipe diameter=2cm, contraction pipe diameter=1.49cm, that is contraction area ratio A1/A2=1.8 a) If water is stationary(pump OFF) and if I drill a hole anywhere at pipe, water will leak out, because pressure(200kPa) inside is higher than atmospheric pressure (101 325Pa). b)If I turn on pump and water start flowing with with v1=10m/s in A1 wider section, from Bernoulli equation I...
