magnetic drag brake
magnetic drag brake
(OP)
First time here, hope I'm in the right area!
I have several very strong magnets out of computer hard drives and I am thinking of using them to create a drag brake for my off road vehicle by holding them close to the rotating drive line. I don't think the walls of the drive line may be too thin and my question is, if I wrap the drive line with a long sheet of aluminum, will the fact that it's layered reduce induced magnetic eddy currents and diminish the drag.
I was thinking to put flat disk around the drive line, I think just getting the magnets close to the drive as it spins will do the job.
If you have any advice, I would sure appreciate your help!

RE: magnetic drag brake
Remember that all of the energy that you put into this device will end up as heat.
These brakes get very hot unless cooled actively.
They are usually magnets on either side of a disc, ala disc brakes.
This help dissipate the heat.
