May 26, 2024 · Magnetic field, a vector field in the neighborhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to line up in the direction of the field.
A magnetic field is a vector field in the neighbourhood of a magnet, electric current, or changing electric field in which magnetic forces are observable. A magnetic field is produced by moving electric charges and intrinsic magnetic moments of elementary particles associated with a fundamental quantum property known as spin.
Mar 9, 2022 · A magnetic field is an invisible force field generated by a magnet (like bar magnet and horseshoe magnet), moving electric charge (like current-carrying wire, toroid, and solenoid), spinning electrons, and changing electric field.
A magnetic field is an invisible space around a magnetic object. It is basically used to describe the distribution of magnetic force around a magnetic object. Magnetic fields are created or produced when the electric charge/current moves within the vicinity of the magnet.
A magnetic field refers to a vector field in the neighbourhood of a magnet, electric current or charging electric field. The region around a magnetic material or a moving electric charge within which the force of magnetism acts is known as the magnetic field.
A magnetic field (sometimes called B-field [1]) is a physical field that describes the magnetic influence on moving electric charges, electric currents, [2] : ch1 [3] and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.
Magnetic fields occur whenever charge is in motion. As more charge is put in more motion, the strength of a magnetic field increases. Magnetism and magnetic fields are one aspect of the electromagnetic force, one of the four fundamental forces of nature.
Since magnetic forces act at a distance, we define a magnetic field to represent magnetic forces. A pictorial representation of magnetic field lines is very useful in visualizing the strength and direction of the magnetic field. The direction of magnetic field lines is defined to be the direction in which the north end of a compass needle points.
Nov 29, 2017 · What is a Magnetic Field? Magnetic fields can be simply described as a field that extends through space, originating from a moving electric charge or from a magnetic dipole. This field can produce a force when acting on another magnetic object.
Magnetic Field. Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits. The magnetic field B is defined in terms of force on moving charge in the Lorentz force law.
