A changing electric induces changing electric fields:
The law of Electromagnetism is Invariance of the Electromagnetic field. The vector or induction portion is "
o = dEv/dr + Del Er + DelxEv = dEv/cdt + Del Er + Del x Ev
this is the same law as Faraday's law but it includes the Gradient Del Er
0= dBv/dt + Del Er + Del xEv

∙ 12y agoAccording to Farady's law the induced emf is the rate of change of the flux and opposes the change. But flux is the surface integral of the magnetic field. So, in this way the change in the magnetic field induces emf.

Can a changing magnetic field produce a steady electric field?
Not a steady but a moving electric field can be produced by ever changing magnetic field.
Why is a vibrating electric field an example of an electromagnetic wave?
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.
Do Electromagnetic waves consist of changing electric and magnetic fields?
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.
How electric current have magnetic effect?
The magnetic force acts only on moving electric charges; A constant electric current produces an unchanging magnetic field and a changing electric current produces a changing magnetic field.
What are two ways to produce electric fields electric fields are produced by charged particles or by changing magnetic fields?
One way to produce an electric field is through the presence of charged particles. When charged particles, such as electrons or protons, are stationary or in motion, they generate an electric field around them. Another way to produce an electric field is through changing magnetic fields. According to Faraday's law of electromagnetic induction, a changing magnetic field induces an electric field, causing the flow of electric charges.
Does an electric current produces a magnetic field?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
Does a moving magnetic field produce an electric current?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
What does a changing magnetic field induce?
An electrical current.

Why does a transformer require alternating current?
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.
What is the classical explanation of a dc electric current in a metallic wave?
A changing magnetic field always produces an electric field, and conversely, a changing electric field always produces a magnetic field. This interaction of electric and magnetic forces gives rise to a condition in space known as an electromagnetic field.
Can an electric field exist without a magnetic field?
An electric field can exist even without the presence of a magnetic field. An example of this is a stationary electric field.
How electric current have magnetic effect?
The magnetic force acts only on moving electric charges; A constant electric current produces an unchanging magnetic field and a changing electric current produces a changing magnetic field.
Creates a magnetic field?
Both magnetic materials and moving electric charges induce magnetic fields.
