Force between magnet and solenoid

AI Thread Summary
The discussion focuses on the formula for the force between a current-carrying solenoid, both cylindrical and toroidal, and a permanent magnet. It highlights that the force between two permanent magnets is directly proportional to the product of their flux densities at the poles. Participants question whether this formula can be adapted for solenoids by substituting the flux density values and other relevant parameters. The conversation emphasizes the need for clarity on how the solenoid's characteristics affect the force calculation. Understanding these relationships is crucial for accurate applications in electromagnetism.

What have you found in your searching for such formulas so far?
 
so far I've found out the formula for force between two permanent magnets and it states that the force is directly proportional to the product of their flux densities at poles. Now my doubt is that can we use the same formula by substituting the value of flux density and other parameters of solenoid instead of magnet.

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
