Shielding Material data?

[yasmanian]

Hi, i am doing a project on shielding of power frequency magnetic fields from ac power transmission lines.

part of my investigation is looking at different shielding materials. I would be grateful if anyone could guide me to some bh curves and permeability values which i can use in opera 2d for my modeling.

Many thanks.

Hi, thanks for the reply, I should have been more specific, if anyone has links to manufacturers data, i.e real values and bh curves for specific shielding metals.

Carpenter Steel makes some high permeability alloys like Hymu 80 and Hymu 800.
