Transformers can only work with which type of electricity?

As current moves through a conductor, it creates a _______ field.

If direct current moves through a conductor, the magnetic field remains ________.

If we send alternating current through a conductor, the magnetic field increases and decrease in strength and _____________ changes as the current changes direction.

When alternating current moves through the first coil of a transformer the magnetic fields it creates will induce a ____________ in the second coil of the transformer.
