Definition of 'Electromagnetic Waves' Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.
Relationship between magnets and electricity?
The relationship between electricity and magnetism is intimate. A changing magnetic field induces electrical current in a wire, and is the basis for electrical generation. Also, an electrical current flowing through a wire creates a magnetic field, and is the basis for most motors.In general, a changing magnetic field creates an electrical field, and a changing electrical field creates a magnetic field. In fact, light is exactly this; two fields oscillating at right angles, and inducing one another through space.One of the four fundamental forces in the universe is the electromagnetic force. Not the electric or the magnetic force, but the electromagnetic force. Basically, you can't have electricity without magnetism and vice versa. That may not make electricity and magnetism exactly the same, but they are intertwined in a most intimate way.
Name two properties of electromagnetic waves?
They are all transverse waves. They can all travel at the speed of light, 3*10^8 m/s. Able to travel through a vacuum or through a medium. Formed by oscillating magnetic and electric fields. All exibit other characteristics of waves such as reflection, refraction, interference and the Doppler Effect.
A force that draws bodies together?
Chemistry. Hormones. Pheromones. Electric fields, magnetic fields, gravity fields.
Oscillating electric and magnetic fields regenerate each other These oscillating fields perpetuate?
Electromagnetic waves
What is the phase relation between oscillating electric and oscillating magnetic fields in an electromagnetic wave?
The fields are in time phase and space quadrature.
What is the kind of wave formed by an electric fields and a magnetic fields oscillating at right angles to each other?
Electromagnetic wave.
Why do you describe light as electromagnetic radiation?
because light is made up of oscillating electric and magnetic fields
Electromagnetic waves are produced by?
an electric field and a magnetic field both oscillating at the same frequency and orthogonal to each other.
Can electromagnetic wave deflect by electric or magnetic field?
No. An electromagnetic wave IS electric and magnetic fields.
Phase relationship between oscillating electric and magnetic fields?
nothing
What is Created by vibrations in electric and magnetic fields?
Vibrations in electric and magnetic fields create electromagnetic radiation.
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.
How are EM waves produced?
In classical physics, EMR is considered to be produced when charged particles are accelerated by forces acting on them. ( Source: Wikipedia) EMR stands for Electromagnetic radiation. The electromagnetic waves that compose electromagnetic radiation can be imagined as a self-propagating transverse oscillating wave of electric and magnetic fields. The two types of fields in EMR waves are always in phase with each other, and no matter how powerful, have a ratio of electric to magnetic intensity which is fixed and never varies.

Electrical energy to mecanical energy?
they are produced by the vibration of oscillating electric and magnetic fields
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.
