Hi
I have a U shape metal core and want to buy a permanent magnet which I can place between the core's ends "thus completing the flux path through the core". the permanent magnet must not saturate the core, I also have the H-B curve fore the core material.
In the H-B curve, the point at which the material becomes saturated is at 1 "Magnetizing Force-H-Oersteds"
Do I look for a permanent magnet which has less than 1 Magnetizing Force in H-Oersteds? well, they are rated by their energy products number MGOe as in here.
The second thing, I thought the volume of the material in the core must effect the saturation, i.e. the more the volume the more magnetizing force it will need before it gets saturated, well how come the H-B curve does not show this?
Please help me understand those issues.
thx
