How are the poles of a tapered magnet distributed?

AI Thread Summary
The distribution of poles in a tapered magnet can be complex, with magnetic field lines not concentrating as strongly at the apex as one might expect. Finite Element Method (FEM) modeling software is recommended for accurately calculating the magnetic force of such magnets. An example FEM model of a conical magnet illustrates this concept effectively. The discussion highlights the importance of using advanced modeling tools for precise magnetic force calculations. Understanding these principles is crucial for applications involving tapered magnets.

Looks like FEM modeling software is your best bet for finding magnetic force. Below is an example FEM model of a conical magnet that I found online. Note that the magnetic field lines don't concentrate at the apex nearly as strongly as in your hand sketch.

That's a very clear explanation, thank you!

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
