    Normal Polarity
AI Thread 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?
Relevant Equations
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.

Thread 'Minimum mass of a block'

Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...

Thread 'Electric field due to charges between 2 parallel infinite planes'

TL;DR Summary: Find Electric field due to charges between 2 parallel infinite planes using Gauss law at any point Here's the diagram. We have a uniform p (rho) density of charges between 2 infinite planes in the cartesian coordinates system. I used a cube of thickness a that spans from z=-a/2 to z=a/2 as a Gaussian surface, each side of the cube has area A. I know that the field depends only on z since there is translational invariance in x and y directions because the planes are...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
