Just to be crystal clear:
That spinning disc is just all aluminum?
I appreciate all the help. Would a crude equation describing the resistance be:
F = ω * β * A
where;
F: force resisting the disc
ω: rotational velocity of the disk
β: magnetic field strength
A: magnetic field...
Sorry but I'm confused. No, not what? By spatial variation do you mean a distance from the spinning disc variation? If so doesn't a sinusoidal magnetic field strength simulate that? If it is more like having magnets pass by each other would just cycling power on and off to one...
The electromagnet set up with the sinusoidal variation would provide the varying magnetic field to induce the eddy current and braking action. The steady state magnetic field I thought I'd use the magnitude to provide more or less resistance.
I guess what I'd could do is have one...
I ultimately would like to use either one or two electromagnets. With that said and the knowledge that it is a changing magnetic field let me ask you this.
If I change the configuration so that on one side of the aluminum wheel I'm spinning is an electromagnet facing the wheel with a 1/16"...
I am an electrical engineer disabled in a snow sking accident and am now a quadriplegic. I'd like to design an exercise arm bike and make it magnetically resisted because friction resisted is not conducive to minute changes in resistance.
I have a magnetic resisted trainer for a road...
