What is the relationship between the magnetic field and electric field in electromagnetic waves?
In electromagnetic waves, the magnetic field and electric field are perpendicular to each other and oscillate in sync. When one field changes, it induces a change in the other field, creating a self-sustaining wave that propagates through space.
How does a vibrating electric charge produce an electromagnetic wave?
When an electric charge vibrates, it creates changing electric and magnetic fields. These changing fields propagate through space, creating electromagnetic waves. The oscillating electric field produces a magnetic field, and the changing magnetic field then produces an electric field, thus creating a self-sustaining wave.
How does a rotating dipole radiation affect the electromagnetic field around it?
A rotating dipole radiation causes the electromagnetic field around it to change direction and strength periodically. This results in the emission of electromagnetic waves in all directions, similar to a spinning top creating ripples in water.
When electric and magnetic fields both exist it is called an?
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.
What would happen if you made an electromagnetic field?
Creating an electromagnetic field involves generating magnetic and electric fields. The effect of this field depends on its strength and frequency. For example, low-frequency electromagnetic fields are common in everyday appliances and are generally safe, while high-frequency fields like those from radio waves or x-rays can have health risks if exposure is prolonged.
Why emf is not zero when field current is zero?
Even when the field current is zero, there can still be a residual magnetic field present in the system, which can induce an electromotive force (emf) in a nearby conductor. This phenomenon is explained by Faraday's law of electromagnetic induction, where a changing magnetic field can induce a voltage in a closed loop.
What is the phase difference between electric and magnetic field?
In an electromagnetic wave, the phase difference between the electric and magnetic fields is 90 degrees. This means that when the electric field is at its maximum value, the magnetic field is zero, and vice versa. This relationship is essential for understanding how electromagnetic waves propagate through space.

If a conductor carrying an alternating current were formed into a coil the magnetic field that is generated?
would induce a current in the coil itself, creating a self-induced electromagnetic field. This field would interact with the original field, leading to a stronger magnetic effect and potentially affecting nearby conductors or devices. The coil's shape and number of turns would also impact the strength and direction of the induced field.

What determines the direction of polarization of a radiated electromagnetic field?
The polarization of an electromagnetic field is defined as the direction of its E field (electrostatic).
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.
How does electromagnetic induction work to generate electricity?
Electromagnetic induction is the process of creating an electric current in a conductor by moving it through a magnetic field or by changing the magnetic field around it. This movement or change in magnetic field induces a flow of electrons, generating electricity. This principle is used in devices like generators to produce electrical power.
