9 paź 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 (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.
22 paź 2016 · Definition: Magnetic fields can be defined in a number of ways, depending on the context. However, in general terms, it is an invisible field that exerts magnetic force on substances...
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.
2 lut 2022 · Magnetism is a force of nature produced by moving electric charges. Sometimes these motions are microscopic and inside of a material known as magnets. Magnets, or the magnetic...
29 lis 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.
