Why do laminated transformer cores reduce heating while still allowing strong transformer action?
A
The laminations remove all changing magnetic flux from the core.
B
The laminations interrupt large eddy-current loops but still provide a magnetic path.
C
The laminations make current flow directly from primary to secondary.
D
The laminations force the transformer to operate only on DC.
