I'm not looking for how to calculate the gravity force acting on a mass.
I'm interested in calculating the breaking force acting on the falling magnet as it falls through the coil.
So to sum up: I need a general equation for the breaking force acting on the magnet as...
I want to know how to calculate the braking force acting on a magnet falling through a copper tube.
The setup can be seen in this video (YouTube, @ 1:49 - 3:12): Copper's Surprising Reaction to Strong Magnets.
Note that it's not a copper tube in the video but a plastic tube surrounded by a...
I must apologise for any confusion. Let me try again:
The wikipedia article that you linked was very informative. I'll use its description to explain my problem.
Please read the text in the attached screenshot.
After you've read the text, notice the red box in the bottom with the marked word...
I'm glad I'm not the only one who didn't understand it - thought I was missing something.
But let's forget about the articles, τres,x and the formulas from the table.
I'm interested in finding a relation between τx and τy.
I found this website (see the bottom 'Mathematical Discussion')...
Sure thing! Here you go:

Here's another article talking about the same formulas:
Gyroscope Mystery is Solved
I'm not really sure how to describe the 'resisting torque'.
I'm not thinking about Newton's 3rd law.
I feel that whenever I try to apply a torque to my spinning gyroscope, it tries to resist the motion around the applied torque's axis. But I'm not 100% that this is what is happening. Maybe it...
Hi,
Say there's a gyroscope with moments of inertia Ix, Iy and Iz spinning around a vertical z-axis (see attached illustration) with a given angular velocity ωz. Notice that the gyroscope is floating in space as in that there's no gravity acting on the gyroscope.
Now I apply a torque τx...
