Is each sheet of silicon steel to be insulated?
However, an alternating magnetic field will produce a cable in the core. If the silicon steel sheet is a whole, its electrical conductivity will be greatly enhanced, and the eddy current will be generated, which is equivalent to a closed circuit. Therefore, the iron core of the transformer is stacked with the thin silicon steel sheets which are insulated from each other.
Yes, the silicon steel sheet has the advantages of good magnetic conductivity and poor electrical conductivity. It is the use of this characteristic that the primary stage coil achieves the effect of variable pressure by electromagnetic induction.
