What waves are combination of electric field and magnetic field?

Electromagnetic waves are the combination of electric and magnetic field waves produced by moving charges.

Are combinations of electric field and magnetic field?

The electromagnetic field propagates at the speed of light (in fact, this field can be identified as light) and interacts with charges and currents. The field can be viewed as the combination of an electric field and a magnetic field.

What is the relation between the strength of the magnetic field and the electric field when you consider a plane wave of electromagnetic radiation in the medium?

But in an EM wave, the electric field and magnetic field carry the same energy. So in an EM wave, the magnitude of the electric field is proportional to the magnitude of the magnetic field, and the proportionality constant is c, the speed of light!

What is the relationship between the magnetic and electric fields along the path of a moving electromagnetic wave?

The magnetic field of the electromagnetic wave is perpendicular to the electric field and has magnitude Brad = Erad/c in free space. For electromagnetic waves E and B are always perpendicular to each other and perpendicular to the direction of propagation. The direction of propagation is the direction of E × B.

How do magnitude of electric and magnetic field affects the propagation of the electromagnetic wave?

Once created, the fields carry energy away from a source. Clearly, the larger the strength of the electric and magnetic fields, the more work they can do and the greater the energy the electromagnetic wave carries. A wave’s energy is proportional to its amplitude squared (E2 or B2).

How does an electric field create a magnetic field?

As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field.

Does changing magnetic field produce an electric field and a changing electric field produces a magnetic field?

Then they cannot be treated independently of each other, because the changing electric field produces a changing magnetic field and the newly produced changing magnetic field produces a changing electric field, which is an electromagnetic wave.

How are electric and magnetic fields similar?

Similarities between magnetic fields and electric fields: Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). Like poles repel; unlike poles attract.

What is the relationship between the wave and the field?

A wave is a particular time-dependent pattern within a field which follows the mathematics of the wave equation, and the field is the medium. For example, an electromagnetic wave is a pattern (usually oscillatory in space and time) in the electromagnetic field.

What is the relationship between the wavelength frequency and energy of electromagnetic waves?

Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν.
