Not a steady but a moving electric field can be produced by ever changing magnetic field.

What causes an electric current to keep moving is a steady supply of electrons.
Steady temperature is the temperature which does not vary over time but remains constant with the changing time. Usually this steady state is achieved and we record the different readings to anlayse a process its efficiency.

Yes. A steady current will produce a magnetic field, B= uI/r
Gauss's law: Electric charges produce an electric field. Gauss's law for magnetism: There are no magnetic monopoles. Faraday's law: Time-varying magnetic fields produce an electric field. Ampère's law: Steady currents and time-varying electric fields produce a magnetic field.
In an AC circuit it is the fluctuation of the sine wave which causes a varying magnetic field which in turn induces a current to flow in the secondary.

The 3-phase currents in the 3 coils of an induction motor will produce a steady rotating magnetic field.
Well, first of all, nobody ever claimed that the energy is stored 'in the inductor'.The energy is stored in the inductor's magnetic field.Next: When they say that energy is stored, it doesn't necessarily mean that it'sstored like in a box or a jar, and you can fill it up, put it up on the shelf, then comeback and get it in a few days.The energy stored in the magnetic field is steady as long as the current through theinductor is steady. If the current is changing, then the energy in the magnetic fieldis also changing. When the energy in the magnetic field is decreasing, then of coursethe magnetic field is returning some of its stored energy to the circuit, by way of thecurrent.
Plain old electricity. There's only one kind.
A current carrying conductor, such as a metal wire, will produce a magnetic field around it because of the motion of charge within the wire itself. This motion produces or sets up a magnetic field around the wire in the form of concentric circles. This electromagnetic effect is described in physics by the Biot-Savart Law, an experimentally deduced inverse-square law. The effect is also described by Ampère's Law, which is derived from the Biot-Savart Law. This law relates magnetic field and current. Also, a magnetic field that is set up by an electrical current will produce a magnetic force. This force depends on the rate of charge transfer and the magnetic field. The force produced by a current-carrying wire depends on the length, the magnetic field, and the current, which is the charge flow per unit of time.
