# Question: What is magnetic field of electric current?

Contents

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.

## What is the magnetic field of electric?

Magnetic fields can be used to make electricity

Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy.

## What is current magnetic field?

Electric current produces a magnetic field. This magnetic field can be visualized as a pattern of circular field lines surrounding a wire. One way to explore the direction of a magnetic field is with a compass, as shown by a long straight current-carrying wire in.

## What do you mean by magnetic field?

: the portion of space near a magnetic body or a current-carrying body in which the magnetic forces due to the body or current can be detected.

## What is magnetic field short answer?

The magnetic field is the area around a magnet in which there is magnetic force. Moving electric charges can make magnetic fields. … In physics, the magnetic field is a field that passes through space and which makes a magnetic force move electric charges and magnetic dipoles.

## How electric field is created?

The electric force acts over the distance separating the two objects. … The space surrounding a charged object is affected by the presence of the charge; an electric field is established in that space. A charged object creates an electric field – an alteration of the space or field in the region that surrounds it.

## What is the formula for magnetic field?

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 causes a magnetic field?

All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

## What is the magnetic field symbol?

Symbols for physical quantities and their international units

symbol quantity symbol
σ conductivity S/m
FB, FB magnetic force N
B, B magnetic field T
ΦB magnetic flux Wb

## What is the best definition of a magnetic field?

The definition of a magnetic field is a place in space near a magnet or an electric current where a physical field is created from a moving electric charge that creates force on another moving electric charge. An example of a magnetic field is the Earth’s magnetic field.

## What is another name for magnetic field?

magnetic flux; flux; field; field of force; force field.

## What do you mean by magnetic field Class 6?

The magnetic field is a region or space where there is an influence of a magnet. … All types of magnets have two poles; North Pole which is indicated by ‘N’ and South Pole which is indicated by ‘S’. Irrespective of shape every magnet has a field around it.

## Where is a magnetic field?

Learn about magnetic fields and interactions between magnetic poles. magnetic field, a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable.

## What is magnetic field class 10th?

Magnetic field: The area around a magnet where a magnetic force is experienced is called the magnetic field. It is a quantity that has both direction and magnitude, (i.e., Vector quantity). Magnetic field and field lines: The influence of force surrounding a magnet is called magnetic field.

## What is magnetic field and its unit?

The SI unit for magnetic field is the Tesla, which can be seen from the magnetic part of the Lorentz force law Fmagnetic = qvB to be composed of (Newton x second)/(Coulomb x meter). … A smaller magnetic field unit is the Gauss (1 Tesla = 10,000 Gauss).
