What do you mean by electromagnetic field?
electromagnetic field, a property of space caused by the motion of an electric charge. A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. An electric field can be produced also by a changing magnetic field.
Where is the electromagnetic field?
Electromagnetic fields are present everywhere in our environment but are invisible to the human eye. Electric fields are produced by the local build-up of electric charges in the atmosphere associated with thunderstorms.
What is electromagnetic field Class 10?
An electromagnetic field is referred to as a physical field of objects that are charged electrically. … It is an electric and magnetic field combination and is often considered as the electromagnetic field sources.
What is electromagnetic field and wave?
Electromagnetic radiation, is a form of energy emitted by moving charged particles. As it travels through space it behaves like a wave, and has an oscillating electric field component and an oscillating magnetic field. These waves oscillate perpendicularly to and in phase with one another.
What is an electromagnetic field made of?
Electromagnetic fields are made out of photons. The magnitude and direction of the electromagnetic field intensity at any point is directly proportional to the magnitude and direction of the force of the photon at that point.
What is an example of an electromagnetic?
Radio waves, microwaves, visible light, and x rays are all examples of electromagnetic waves that differ from each other in wavelength. … Electromagnetic waves are produced by the motion of electrically charged particles.
Are humans electromagnetic?
The human is a electromagnetic field or is like a electron that come form the electromagnetic field . the photon is a electron magnetic field and it generates the electron and positron. The photon may also be a resultant of an electromagnetic field .
What causes electromagnetic?
Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom. When the electron returns to its original position, an electromagnetic wave is produced. … These electrons in these atoms are then in a high energy state.
What cause a magnetic field?
When an electric charge moves it generates a magnetic field. … When an electric current flows it generates a magnetic field because an electric current is moving charges. Electromagnets are made from strong electric currents flowing through a coil of wire.
What is electromagnetic field Class 12?
Electric field is a force produced by a charge near its surroundings. This force is exerted on other charges when brought in the vicinity of this field. SI unit of electric field is N/C (Force/Charge).
What is electromagnetic field Class 11?
The electric field is defined mathematically as a vector field that can be associated with each point in space, the force per unit charge exerted on a positive test charge at rest at that point. The electric field is generated by the electric charge or by time-varying magnetic fields.
What is electromagnetic force class 11th?
Electromagnetic Force: It is the force between charged particles. Charges at rest have electric attraction (between unlike charges) and repulsion (between like charges). … Together they are called Electromagnetic Force.
What is a field in physics?
field, In physics, a region in which each point is affected by a force. Objects fall to the ground because they are affected by the force of earth’s gravitational field (see gravitation). … See also electromagnetic field.
What is magnetic field formula?
The magnitude of the force on a wire carrying current I with length L in a magnetic field is given by the equation. … F=ILBsinθ where θ is the angle between the wire and the magnetic field. The force is perpendicular to the field and the current.
What is the difference of electric field and magnetic field?
The electric field is actually the force per unit charge experienced by a non moving point charge at any given location within the field, whereas the magnetic field is detected by the force it exerts on other magnetic particles and moving electric charges.
