Electromagnetic fields can be varying in intensity. A magnet is static.
Transverse modes are classified into different types:TE modes (Transverse Electric) no electric field in the direction of propagation.TM modes (Transverse Magnetic) no magnetic field in the direction of propagation.TEM modes (Transverse Electromagnetic) no electric nor magnetic field in the direction of propagation.Hybrid modes nonzero electric and magnetic fields in the direction of propagation.
An electromagnetic field.
yes.magnetic field present around the conductor.current and magnetic fields are inter related..with current we can produce magnetic field and vice versa
An electromagnetic wave is properly called a Transverse Electro Magnetic wave, or TEM wave. It consists of an alternating magnetic wave at right angles to an alternating electric wave, with both fields being at right angles to the direction of propagation. The plane of the electric field is defined as the plane of polarization.
we make use of the observation that a charge (whether magnetic or electric, hence electromagnetic) in a field experiences force. For example, a wire carrying a current builds up a magnetic field around it, and when we place something with a magnetic charge near it (like a compass needle) it pushes the needle to try to line it up with the field (it's definitely not that simple, but it works unless you start doing the calculus and Fourier Transforms). Another neat trick; if we bring a second wire close to the first wire carrying the current, the field pushes on the electrons in the second wire and that tries to make a current in the second wire. This trick works on almost all electromagnetic fields, whether made by current flowing or by something else.
Yes, an electromagnetic field refers to the combination of electric and magnetic fields that are generated by electric charges and changing magnetic fields. This field propagates through space and carries electromagnetic energy.
An electromagnetic field is a physical field produced by electrically charged particles. It consists of electric fields and magnetic fields that interact with each other. When both electric and magnetic fields coexist, they form an electromagnetic field.
Not quite. An electromagnetic field is formed when electric and magnetic fields oscillate together perpendicularly to each other. So, a situation where both magnetic and electric fields are present and oscillating in a coordinated manner is what creates an electromagnetic field.
electromagnetic
"Electromagnetic" refers to the interaction between electric and magnetic fields. A magnetic field is a region around a magnet where magnetic forces are detected. When an electric current flows through a conductor, it creates a magnetic field around it, resulting in the generation of an electromagnetic field.
Not really. You could have both an electric field and a magnetic field occupying the same space at the same time but they wouldn't 'make the definition' of electromagnetic until they began to fluxuate in phase at a harmonized frequency.
A temporary magnetic field created by a flowing electrical current is an electromagnetic field. Stop the current from flowing, it goes away.
Magnetic field
In an electromagnetic wave, the changing electric field creates a magnetic field, and the changing magnetic field in turn regenerates the electric field. This process continues as the wave propagates through space, leading to the self-sustaining nature of electromagnetic waves.
Gamma rays are not affected by magnetic and electromagnetic fields because they are neutral in charge and do not have a deflected path in the presence of these fields.
Yes, light is created by vibrations in electromagnetic fields. When an electric field oscillates, it generates a corresponding magnetic field, and vice versa. These oscillating electric and magnetic fields together form electromagnetic waves, which we perceive as light.
The question founders on the rocks of a chicken/egg conundrum. The presence of both an electric field and a magnetic field is required in order to produce an electromagnetic wave.
