Potential Energy between two magnets, and potential energy of gas

[dmanofdland]

Hello everyone,

I'm trying to come up with modeling for one of my experiments and I was wondering if I could get some help. I've piston that is going to be levitated using two magnets: north facing north or south facing south. I'm going to be using the repelling effect of the magnets to levitate this piston. I was wondering how I can find the potential energy of the two magnets.

I was also wondering if someone can guide me to find potential energy of gas that is being compressed due to increase in heat.

Thank you.

PS: My experiment is for Stirling engine, so the increase in temperature causes a piston to move which in turn compresses the gas, then decompresses and compresses it again. This cycle goes on for a while.

Thank you for reaching out for assistance with your experiment. I am happy to offer my expertise and guidance.

To find the potential energy of the two magnets, you will need to use the formula for magnetic potential energy, which is U = -m1m2/r, where m1 and m2 are the magnetic moments of the two magnets and r is the distance between them. You will also need to consider the direction of the magnetic field and the orientation of the magnets in relation to each other.

To find the potential energy of the compressed gas, you will need to use the formula for internal energy, which is U = nCvΔT, where n is the number of moles of gas, Cv is the specific heat capacity at constant volume, and ΔT is the change in temperature. This will give you the internal energy of the gas, which can then be converted to potential energy using the appropriate conversion factor.

I hope this helps you in your experiment. Best of luck with your Stirling engine project!
