Is Type B Better? Thanks

For completeness, we would measure current phase angle. Current can be lower due to higher permeability or lower losses.

The core material with the lowest losses, all other things kept identical, is the best. When I say all other things should be identical, I mean IDENTICAL. Including the applied voltage.
