Calculating Magnetic Forces: Theory and Methods

AI Thread Summary
To calculate the forces between two magnets, particularly with one stationary and the other moving, understanding both the energy method and the Maxwell stress tensor is essential. The discussion highlights a need for accessible resources that explain these concepts clearly, especially for those struggling with the mathematical aspects. Participants are encouraged to share articles, websites, or other materials that simplify these theories. The focus is on finding effective learning tools to grasp the calculations involved in magnetic force interactions. Comprehensive resources will aid in mastering the theoretical and mathematical foundations necessary for this topic.

Hello,

I am trying to calculate the forces between two magnets and i need some good background in theory and maths (i am struggle with maths :frown:). I found some materials on internet but i can not understand yet!
Exactly, i have two magnets where the one is stationary and the other is moving and i am interesting to caclulate the forces between the two magnets by using two methods:
1) the energy method
2) the Maxwell stress tensor

So, does anyone can suggest me any good materials, e.g. articles, websites, etc

Thanks in advance

Kind Regards

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...
