In the real world yes-ish. In the case of a a roller coaster or car the eddy currents bring the speed to near 0 & the rolling friction brings it to a complete stop. The issue is an eddy current braking system can’t keep something at rest. That’s why the roller coaster has a physical brake to keep the ride in place when people are getting on. There are other types of magnetic brakes/ contactless brakes, I just don’t know much about them. My company used the eddy current brakes to limit fall speeds to a safe level if a specific part fell during an emergency.

Idk it might use magnetic brake pads. I have used them in other fields & they are pretty nifty. The ones I used created eddy currents & had not mechanical wear. For my project the mechanical brake had a ~10 year lifespan while the magnetic brake could last ~50 years. Also the mag brake was only 30% more expensive but didn’t need maintenance & would be significantly cheaper if you took the lifespan of the project.

Why not throw it into chatgpt to change the image from bitcoin to Ai? /s

We already tried that. It didn’t have the best results. :/
