What is a magnetic field will be produced at some point in space if the electric field at the point?
As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.
What are two fields surround a moving electric charge?
A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.
Why photon cannot be deflected by electric and magnetic field?
a photon cannot be deflected by an electric or magnetic field because it has no charge and no magnetic poles like elementary particles such as the electron
Creates a magnetic field?
Both magnetic materials and moving electric charges induce magnetic fields.
What are electromagnetic oscillators?
when a charge oscillates for example in a capacitor it produce an electric field; which in turns produce a magnetic field in an inductance. the magnetic field oscillates perpendicular to the electric field and an electromagnetic waves perpendicular to both is produced.
When and magnetic fields both exist it is called an electric magnetic field?
electromagnetic
Which wave cannot exist inside wave guide?
TEM TE modes (Transverse Electric) have no electric field in the direction of propagation. * TM modes (Transverse Magnetic) have no magnetic field in the direction of propagation. * TEM modes (Transverse ElectroMagnetic) have no electric nor magnetic field in the direction of propagation. * Hybrid modes are those which have both electric and magnetic field components in the direction of propagation

Which of the following are created by an arrangement of electric charge or a current?
for apex its: a quantum field, a gravitational 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.
Electric field in total magnetic field?
Electric field and magnetic field are two quite different things, and not necessarily related.
Does light produce both electric and magnetic field?
light exhibit magnetic field but i cant say about electric Field...
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.
What electromagnetic waves?
Electromagnetic waves are transverse (unpolarized or polarized) or circularly polarized waves that have some electrical properties and some magnetic properties. An electromagnetic wave consists of changing electric and magnetic fields. The repeated cyclic transfer of energy from the electric field (weakening it) to the magnetic field (strengthening it) until the electric field is gone, then from the magnetic field (weakening it) to the electric field (strengthening it) until the magnetic field is gone every cycle is the process by which electromagnetic waves propagate without requiring a medium (and is described in Maxwell's Equations).
Can you make a magnet without using a magnetic material Explain?
If you are referring to a magnet as an object that possesses a permanent magnetic field, then yes. There are three circumstances where magnetic fields exist, but not as a result of a permanent magnet. 1. Electric current causes a magnetic field. Thus, any wire carrying a current or even a current without a wire (like a lightning bolt) will be surrounded by a magnetic field. Since electric current is made up of moving electric charges, it is actually true than any moving electric charge creates a magnetic field. 2. It is difficult to observe outside of a scientific laboratory, but when there is an electric field that is varying in time, that creates a magnetic field. Though not easy to demonstrate directly, this turns out the physical phenomena the allows the creation of elecrtromagnetic waves, e.g. like the light we see with our eyes. 3. Thirdly, one can cause materials that are not able to work as permanent magnets to act as temporary magnets. This is the basis for electromagnets. A steel or iron core with an electric current running through a coil surrounding the core will produce a magnetic field. If you simply cut off the power source, the electric current will no longer flow through the coil. No electric current, no magnetic field. When a non-permanent magnet is created, the magnetic field it produces is just the same as the magnetic field of a permanent magnet, until the source is removed and the field disappears. All of these matters together are an essential part of the basics of electromagnetism which describes how and why the phenomena work.
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.
How can it be shown that a magnetic field exist around a wire though which a direct electric current is passing?
The magnetic field can easily be detected with a permanent magnet that is free to move - for example a compass (which has a magnetic needle), or a magnet hanging on a string.
