Quick Answer: What do you mean by electromagnetic force?

The fundamental force associated with electric and magnetic fields. The electromagnetic force is carried by the photon and is responsible for atomic structure, chemical reactions, the attractive and repulsive forces associated with electrical charge and magnetism, and all other electromagnetic phenomena.

What is electromagnetic force Class 11?

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 electromagnetic force and its formula?

Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric field E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by F = qE + qv × B.

What is electromagnetic force Class 8?

The electromagnetic force is a type of physical interaction that occurs between electrically charged particles. It acts between charged particles and is the combination of all magnetic and electrical forces. The electromagnetic force can be attractive or repulsive.

What is electromagnetic induction class 10?

The production of Electricity from Magnetism is called Electromagnetic Induction. We can produce current by. Moving conducting Wire inside a Fixed Magnetic Field. (Hence, if we keep a conducting wire near the magnetic field of magnet and move it vigorously, current will be induced in it.) or.

What is unit of electromagnetic force?

See all related content → Despite its name, electromotive force is not actually a force. It is commonly measured in units of volts, equivalent in the metre–kilogram–second system to one joule per coulomb of electric charge.

What is electromagnetic force quizlet?

electromagnetic force. the attraction or repulsion between charged particles. electromagnetic force holds negatively charged electrons to the positively charged nuclei of atoms.

Who discovered electromagnetic force?

The discovery of electromagnetic induction was made almost simultaneously, although independently, by Michael Faraday, who was first to make the discovery in 1831, and Joseph Henry in 1832.

What is force Class 8 answer?

Answer: A force is simply defined as a push or a pull on a particular object. As per the Class 8 chapter on Force and Pressure, the use of force requires interaction between at least two objects.

What is force in science class 8?

Force: a push or a pull on an object is called force. Force may impart motion to an object. • it is applied on an object in the same direction add to one another. • Magnitude: the strength of a force is usually expressed by its magnitude.

What is an electromagnet Class 7?

Answer: An electromagnet is a coil of insulated wire wound around a piece of a magnetic substance such as soft iron. The magnetic substance acts as a magnet as long as the current flows in the wire.

What is electromagnetic induction class 12th?

The electromagnetic induction is a phenomenon in which an electric field or an electromotive force is induced or created in a conductor by the effect of a changing magnetic field in which the conductor is placed.

What is electromagnetic induction in simple words?

Electromagnetic induction is the process of generating electric current with a magnetic field. It occurs whenever a magnetic field and an electric conductor, such as a coil of wire, move relative to one another.

What is magnetic induction class 12?

The generation of an electromotive force across an electrical conductor in a changing magnetic field is known as magnetic induction. … In other words, magnetic induction is the process of generating magnetism in a piece of magnetic material that is not normally magnetic.
