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
|FB, FB||magnetic force||N|
|B, B||magnetic field||T|
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).
