A tranformer can be made to work on DC if a converter in the circuit is used. It has been done in the past by Using a Megatron system. The idea is to make or break the magnetic flux so time changes occur in the magnetic field. The rate of change of magnetic field with time produces a voltage ;hence a current flow.With out a changing field the transformer acts just as an inductor storing a power charge going no where.
It was Nikola Tesla that solved that problem by inventing the 3 phase alternating current system which changed the field on a per seconds basis. So a transformer is more feasible to use with a non direct current system. It is more economical.

No ..you need a constantly changing magnetic field for it to work.. that means an a.c. current. You can get DC to work, but you have to chop it. That is turn it into a pulse train. To comment on another answer, a megnetron is the tube that makes microwaves in your microwave oven. It is not used in the way described.

no, we need changing electric field to get induced electrc current on the other side of transformer.
