The new generator no effect counter B. EMF part 2 ( Selfrunning )

I have dificulty with construction with laminations, so this is going to take time, or I could use ferrite cores (small version) but this also will take time..

and because I don't want you to wait for me, but rather everyone build his own one..  so I decide to make some drawings and explanations so everybody will understand the idea.

I am drawing them now..

Thanks, I'm looking forward to seeing them

Hey brad in my experiments the ferrite did not work nearly as well as steel laminates. It was explained by arenas and Matt that it's because the poles can't as flip as fast. I'm trying to work out where to get soft iron like syair used. Paul Babcock swears by steel shot but its a bit hard to get in melbourne.

Ferrite will transition much faster that iron or steel,this is why they use ferrite in high frequency transformers or inductors. Steel and iron hold residual magnetism quite well-im guessing you have a few magnetised screwdrivers lying around?. See how much magnetised ferrite you have that wasnt a magnet to start with-my guess is none.

Mmm interesting. I tried ferrites and mumetal. ( left over from Orbos) laminate steel worked best for output. As shown in your vid they certainly had more drag. I don't pretend to understand why, I just follow the data

A couple of properties that make soft ferrites desirable compared to iron or steel:  Much higher resistivity.  Eddy currents are much lower.  Low remanent flux.  Low hysteresis.  The much higher resistivity more than anything else makes them more suitable for higher frequency operation than iron or steel.
