RE: CT mag. curve
However, for most current transformer operating in the lower region, the flux and the magnetization current can be approximated to a linear relationship.

RE: CT mag. curve
When an external magnetic field is applied, the Bloch domains are forced to orient themselves to the direction given by that external magnetic field. To make this happen, the magnetic field has to have enough ‘strength’ to beat the attraction-repulsion forces existing in the natural status of the material. The stronger the field (magnetic field intensity H), the easier to follow the new orientation for the Bloch domains. This explains somehow the non-linearity of the B-vs-H characteristic.
