The Earth's electromagnetic field is generated by the movement of molten iron in its outer core. If this movement were to stop due to the core solidifying, the Earth's magnetic field could weaken or possibly cease altogether. Another possibility could be a significant disruption caused by a massive asteroid impact or a geomagnetic reversal.
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.
Solar flares and coronal mass ejections (CMEs) are the particles that are thrown off the Sun's corona and can affect Earth's magnetic field. These events release energetic particles and electromagnetic radiation that can disturb the Earth's magnetosphere and cause geomagnetic storms.
EMF (electromagnetic field) is a continuous field of electromagnetic radiation, while EMP (electromagnetic pulse) is a sudden burst of electromagnetic energy. EMF can interfere with electronic devices over time, while EMP can cause immediate and severe damage to electronic devices by overwhelming their circuits.
The fringing field in electromagnetic field theory is important because it represents the field outside the main region of interest, providing valuable information about the behavior of the electromagnetic field. Understanding the fringing field helps in accurately predicting the interactions and effects of electromagnetic fields in various applications, such as in antennas, sensors, and electronic devices.
There is a motor in a generator which carries out this electromagnetic induction,as we switch on the generator the magnetic field lines between that motor get cuts off by the rotating coil which cause change in flux and change in flux cause induced emf,cue to emf at different points of coil cause current to get flow and then generator will get on.
electricity causes an electromagnetic field, also radiation.
Changes in the magnetic field
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
The size of the moons electro-magnetic field is proportional to the composition of it's core(not unlike an iron core from a electromagnet), the insulation of the core to the outer surface(not unlike the outer windings of an electro-magnet) and whatever atmosphere it may have. It is approxamately 83% the size of the Earths electromagnetic-field.
An electromagnetic wave is a form of radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge. An electromagnetic wave travels like any other form of radiation or light, except for the fact that an electromagnetic wave moves perpendicular to an electric field and a magnetic field.
This question is slightly back to front. It should perhaps read - can an electromagnetic wave ever not move ? The answer to this question would be no. Motion is absolutely central to the very existence of an electromagnetic wave. If the voltage between two conductors varies up and down, the electric field between them does the same. This changing electric field causes a changing magnetic field. The changing magnetic field causes a changing electric field, and so on ad infinitum. The net result of all this is an electromagnetic wave which propagates outwards at the speed of light.* If the wave were somehow prevented from moving it would cease to exist. * not really surprising, because light is itself an electromagnetic wave.

The polarization of an electromagnetic field is defined as the direction of its E field (electrostatic).
EMF (electromagnetic field) is a continuous field of electromagnetic radiation, while EMP (electromagnetic pulse) is a sudden burst of electromagnetic energy. EMF can interfere with electronic devices over time, while EMP can cause immediate and severe damage to electronic devices by overwhelming their circuits.
It is made by the movement of the earths core and magma field
Yes, Birds are believed as well as other animals to have an innate sense of direction, or a "built-in compass" by earth's magnetic field. Concerns have arisen about electromagnetic interference with their internal compasses and our radio and other electromagnetic transmissions, such as the theory of why Bees are seemingly disappearing.
