Why should a silicon steel sheet of transformer be folded crosswise?
The current generated heat to melt the core (even the whole induction furnace is the use of this principle to melt iron)
Since the resistance and cross-sectional area of a conductor are related, if the resistance is very small with a full magnet, the current generated in the core is very large
The core of the transformer is stacked with insulated silicon steel sheets to minimize the current of the iron core and reduce losses.
