    Magnet Pendulum
AI Thread Summary
The discussion centers on how a bar magnet's intensity affects the stopping time of a swinging metal pendulum positioned above its equilibrium. When a magnet is placed below the pendulum, it creates a magnetic force that interacts with the pendulum's motion. The stronger the magnet, the greater the opposing force, which can increase the time it takes for the pendulum to come to a stop. The theory of equilibrium suggests that the pendulum will eventually reach a state where the forces acting on it balance out. Understanding these dynamics is crucial for grasping the overall impact of magnetic intensity on pendulum motion.

There is an swinging metal pendulum. I put one polar of bar magnet below the equilibrium. What will be the effect of the intensity of the magnet to the time taken for the pendulum to stop? Please explain the theory specifically since I am quite confused. Thank you very much.

How do you understand it so far on your own?

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
