Hace 3 días · A magnetic field (sometimes called B-field) is a physical field that describes the magnetic influence on moving electric charges, electric currents,: ch1 and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.
6 de jun. de 2024 · Electromagnetic field, a property of space caused by the motion of an electric charge. A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced.
13 de jun. de 2024 · The solar cycle is the cycle that the Sun’s magnetic field goes through approximately every 11 years. Our Sun is a huge ball of electrically-charged hot gas. This charged gas moves, generating a powerful magnetic field.
6 de jun. de 2024 · Electromagnetic radiation, in classical physics, the flow of energy at the speed of light through free space or through a material medium in the form of the electric and magnetic fields that make up electromagnetic waves such as radio waves and visible light.
13 de jun. de 2024 · In the ionosphere, charged particles are affected by the magnetic fields of both Earth and the sun. This is where auroras happen. Those are the bright, beautiful bands of light that you sometimes see near Earth’s poles.
Hace 4 días · The magnetic field is an abstract entity that describes the influence of magnetic forces in a region. Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position.
21 de jun. de 2024 · Magnetic field strength, the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself. It is expressed in units of amperes per meter. Learn more about magnetic field strength in this article.
