Effective Permeability
- Thread starter SVS
- Start date
Permeability is the ability to let Magnetic Flux through without creating Eddy currents.
like "Resistance" in magnetism, so high permeability means less resistance to magnetism.
"Effective" means that by changing its dimensions, like diameter or length , or winding more turns of wire on the ferrite,adding an air gap, will alter is Permeability.
It usually means the higher the permeability the lower the frequencies are cancelled out, the lower the perm the higher frequencies cancelled out.

Thank you for the reply.
But I need something elaborate!!! I need to understand all the parameters which affects the value of inductance when it is wound on a ferrite core.
One of those is effective permeability.
I wanna know how it is calculated for a Ferrite and stuff...
The second link doesn' t work. Can you please upload it once again?
Thank you in advance!!
