How to couple an electric circuit with a physical model in COMSOL Multiphysics

In this video, I show you how to couple an electric circuit with a physical model in COMSOL Multiphysics. in the first part, a simple example is used to demonstrate how to make and analyze an electric circuit in COMSOL. In the second part, I show you how to couple a physical model of a copper rod from magnetic field physics to an electric circuit consisting of a step voltage and a resistor. In the next video, I show you the comparison between the frequency-dependent model of the copper rod and when the model is analyzed at a fixed freuency.
Finance: N=53
subs=1837
Available budget (N): 1837-100-53*(53+1)=-1125
Storage limit: 2^ln(1837)=183.02

Good! I am also trying to learn to use comsol in these days.

[@HVE]

Good, it can be useful in some situation

[@khemrajramsamooj9334]

do you think a simple test in comsol can be done using a cylindrical conductor with a sum of sine waves going through it, and then loop antenna/coil mounted on the outside of the conductor to see if they can read the signal on the line?

Hi sir ...thank you for your videos...can you help us who we can define a ..user defined non linear equation in comsol multiphysics

I love this video. I seriously need help with a project. Can you be contacted privately via email?
