Hey all, Interestingly enough, I was actually recently feeding some ducks at a nearby pond when I noticed a cool phenomenon that I couldn't explain myself, so I was hoping you guys could assist in that. When you have two air bubbles over a liquid surface, like water, they seem to accelerate...

Hmmmm... So are pencil and paper solutions not possible simply due to the complexity of the magnetic field underneath the rotor (between the rotor and plate)? It seems to me that you can find the net magnitude of eddy currents induced within the plates given a certain magnetic strength and...

Thank you so much for the reply! I will make sure to conduct the experiment with a wide variety of controls and variables, so I can try to obtain a steady trend for the RPM vs. upward force graph :) Say that I did actually know the vector fields of the permanent magnets and the conductivity of...

Hey guys, So I have a bit of an interesting problem to solve here. I'm trying to calculate the upward repulsion force due to eddy currents created in a conductive surface by a rotating magnetic field. I'm doing this for an undergraduate lab project, and want to be able to provide quantifiable...

Hey all! Just wanted to introduce myself! I've been a reader of these forums for quite some years. I'm an undergrad studying Applied Physics with strong interest in astrophysics, special relativity, and electromagnetism! I've been doing a lot of personal research and accumulated questions and...
