Want this question answered?
Not a steady but a moving electric field can be produced by ever changing magnetic field.
The changing electric field will produce a magnetic field; the changing magnetic field will cause an electric field; both will propagate as a wave - an electro-magnetic wave.
An electrical field which is NOT changing.
Yes, that is the whole idea of an electromagnetic waves. A changing electric field generates a changing magnetic field; a changing magnetic field generates a changing electric field; and the two of them propagate as a wave at the speed of light.

what are the consequences of changing a field size
Not a steady but a moving electric field can be produced by ever changing magnetic field.
Changing the data type of a field can lead to data loss or data corruption if the new data type cannot accommodate the existing data. It can also affect any queries, reports, or applications that rely on the field's data type, potentially causing errors or unexpected behavior. It is important to carefully assess the impact and make any necessary adjustments to ensure data integrity before changing a field's data type.
Changing the depth of field.
The changing electric field will produce a magnetic field; the changing magnetic field will cause an electric field; both will propagate as a wave - an electro-magnetic wave.

In order to induce voltage as an output, a changing magnetic field is needed. To create a changing magnetic field in the transformer a changing current and that is an alternating current.
A changing magnetic field generates an electric field and alternating currents are accompanied (or caused) by alternating voltages.

I'm not sure what you are asking, but the answer to your question is possibly Maxwell's Equations.Maxwell's Equations are a set of partial differential equations that describe the cyclic exchange of energy between a changing electrical field and a changing magnetic field. Unfortunately I cannot enter the equations themselves on this site as they require characters in fonts that are not supported by the current Answers.com software.
