It is not producing rotating field on any physical plane &
can not produce torque

Answer / krishna kumar.k

A transformer & an induction motor, which rotates, work on
the same principle of electromagnetic induction. In the case
of a motor, the rotor,which can be compared to the secondary
of a transformer,is wound on physically free to rotate
arrangement and hence it rotates.

But a transformer secondary is physically not designed and
is not free to rotate.

Answer / dharmendra

In transformer both winding are connected magnetically.Also
on same limb.No air gap between primary and secondary.
