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.
An electric field surrounds an electric charge What additional field surrounds a moving electric charge?
Light and all other electromagnetic waves are produced by charged particles. Every charged particle has an electric field surrounding it.
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 is the definition of electromagnetic wave?
Electromagnetic waves were first postulated by James Clerk Maxwell and subsequently confirmed by Heinrich Hertz. Maxwell derived a wave form of the electric and magnetic equations, revealing the wave-like nature of electric and magnetic fields, and their symmetry. Because the speed of EM waves predicted by the wave equation coincided with the measured speed of light, Maxwell concluded that light itself is an EM wave. According to Maxwell's equations, a time-varying electric field generates a magnetic field and vice versa. Therefore, as an oscillating electric field generates an oscillating magnetic field, the magnetic field in turn generates an oscillating electric field, and so on. These oscillating fields together form an electromagnetic wave. A quantum theory of the interaction between electromagnetic radiation and matter such as electrons is described by the theory of quantum electrodynamics.
What is meant by electric and magnetic field?
A magnetic field is a area in which magnetic objects are pushed or pulled. It is caused by the alignment of parts of atoms.A field of force associated with changing electric fields , as when electric charges are in motion. Magnetic fields exert deflective forces on moving electric charges. Most magnets have magnetic fields as a result of the spinning motion of the electrons orbiting the atoms of which they are composed; electromagnets create such fields from electric current moving through coils. Large objects, such as the earth, other planets, and stars, also produce magnetic fields. See Note at magnetism.

What are facts about electromagnetic fields?
An electromagnetic field is a physical field produced by electrically charged objects. The field can be viewed as the combination of an electric field and a magnetic field. The electromagnetic field may be viewed in two distinct ways: a continuous structure or a discrete structure.
Can an electric current be produced by magnetism?
Yes, a moving electric charge creates a magnetic field
Electromagnetic waves are produced by?
an electric field and a magnetic field both oscillating at the same frequency and orthogonal to each other.
How can electromagnetic waves be produced?
Any electric charge undergoing acceleration will produce Electromagnetic waves. This is by far the most common way.If an oscillating electric field is synchronized with an oscillating magnetic field of exactly the same frequency a beam of light will be produce where the two fields are orthogonal in all dimensions.
Is an electric field associated with an electromagnetic wave constant in time?
No, the electric field oscillates in magnitude and direction as it propagates in the electromagnetic wave.
Can electromagnetic wave deflect by electric or magnetic field?
No. An electromagnetic wave IS electric and magnetic fields.
What are parts of an electromagnetic wave?
Electric field and magnetic field
An electric field surrounds an electric charge What additional field surrounds a moving electric charge?
Light and all other electromagnetic waves are produced by charged particles. Every charged particle has an electric field surrounding it.
What does electromagnetic waves means?
An electromagnetic wave, in its simplest description, is a wave that as it propagates keeps converting its magnetic field into an electric field while converting its electric field into a magnetic field.
What is dielectic heating?
Dielectric heating, also known as electronic heating, RF (radio frequency) heating, and high-frequencyheating, is the process in which a high-frequency alternating electric field, or radio wave or microwave electromagnetic radiation heats a dielectric material.
Does an electromagnetic wave have an electric field?
Yes
