"A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials."
Regions of space where magnetic forces are present.
Magnetic Fields: A magnetic field is a physical field produced by an electric charge in motion, which affects other charges or currents in its vicinity.
Electromagnetism: Electromagnetism is a branch of physics that deals with the study of electric and magnetic fields and their interactions with charged particles.
Lorentz Force: The Lorentz force is a force that is experienced by a charged particle in the presence of an electric and magnetic field.
Maxwell's Equations: Maxwell's equations are a set of four equations that describe the behavior of electric and magnetic fields and their interactions with charged particles.
Magnetic Field Lines: Magnetic field lines are imaginary lines that represent the direction and strength of a magnetic field.
Magnetic Reconnection: Magnetic reconnection is a process whereby magnetic field lines are broken and reconnected in a different configuration, releasing energy in the form of heat and kinetic energy.
Magnetosphere: The magnetosphere is the region of space around the Earth that is dominated by Earth's magnetic field.
Solar Wind: The solar wind is a stream of charged particles that emanate from the sun's corona and interact with the Earth's magnetic field, causing the auroras.
Aurora: An aurora is a natural light display in the sky, caused by the interaction of charged particles from the sun with the Earth's magnetic field.
Van Allen Belts: The Van Allen Belts are two regions in the Earth's magnetosphere that contain high-energy charged particles.
Magnetic Storms: Magnetic storms are disturbances in the Earth's magnetic field caused by the interaction of the solar wind with the Earth's magnetosphere.
Space Weather: Space weather refers to the conditions in space that can affect spacecraft, satellites, and other technological systems.
Carrington Event: The Carrington event was a powerful geomagnetic storm that occurred in 1859 and caused widespread disruption of telegraph systems.
Magnetic Dipole: A magnetic dipole is a pair of opposite magnetic poles separated by a small distance, which produces a magnetic field.
Magnetic Monopole: A magnetic monopole is a hypothetical particle that has only one magnetic pole, which does not exist in nature but can be theoretically predicted.
Dipolar Magnetic Fields: These are the magnetic fields generated by a spherical magnetized object having a north and south magnetic pole.
Uniform Magnetic Fields: These are the fields which have an unchanging magnitude and direction in a given region.
Non-uniform Magnetic Fields: These are the fields whose magnitude and direction are not same at all points in a given region.
Reverse Magnetic Fields: These fields occur when the direction of the magnetic field are opposite to the direction of Earth's magnetic field.
Solar Magnetic Fields: These are the magnetic fields which originate from the Sun and interact with the Earth's magnetic field.
Interplanetary Magnetic Fields: These magnetic fields exist in the space between planets in our solar system.
Magnetosphere: It is a region around the Earth that is filled with charged particles and is significantly controlled by the Earth's magnetic field.
Auroral Oval: The auroral oval is a ring of light that encircles the magnetic poles and occurs due to charged particles interacting with Earth's magnetic field.
Magnetic Reconnection: This is the process by which magnetic fields can merge and release energy in the form of charged particles.
Magnetic Fields of Cosmic Objects: Magnetic fields can be found around many other cosmic objects such as planets, stars, and galaxies, etc.
"A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field."
"A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron and attracts or repels other magnets."
"A nonuniform magnetic field exerts minuscule forces on 'nonmagnetic' materials by three other magnetic effects: paramagnetism, diamagnetism, and antiferromagnetism."
"These forces are usually so small they can only be detected by laboratory equipment."
"The three magnetic effects on nonmagnetic materials are paramagnetism, diamagnetism, and antiferromagnetism."
"Magnetic fields surround magnetized materials, electric currents, and electric fields varying in time."
"It is described mathematically by a function assigning a vector to each point of space, called a vector field."
"In electromagnetics, the term 'magnetic field' is used for two distinct but closely related vector fields denoted by the symbols B and H."
"The unit of B, magnetic flux density, is the tesla."
"The unit of H, magnetic field strength, is ampere per meter (A/m)."
"In vacuum, the two fields are related through the vacuum permeability, B/μ0 = H."
"In a magnetized material, the quantities on each side of this equation differ by the magnetization field of the material."
"Magnetic fields are produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin."
"Magnetic fields and electric fields are both components of the electromagnetic force, one of the four fundamental forces of nature."
"Magnetic fields are used throughout modern technology, particularly in electrical engineering and electromechanics."
"Rotating magnetic fields are used in both electric motors and generators."
"The interaction of magnetic fields in electric devices such as transformers is conceptualized and investigated as magnetic circuits."
"Magnetic forces give information about the charge carriers in a material through the Hall effect."
"The Earth produces its own magnetic field, which shields the Earth's ozone layer from the solar wind and is important in navigation using a compass."
