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.
Learn how electric current produces a magnetic field and how to calculate its magnitude and direction using Ampere's law. Explore the force on a current-carrying wire in a magnetic field and the right hand rules for magnetism.
9 mar 2022 · Learn what a magnetic field is, how it is created by moving charges, and how it can be measured and visualized. Explore the types of magnets, Earth's magnetic field, and the difference between magnetic flux and magnetic field.
9 paź 2024 · magnetic field, a vector field in the neighbourhood 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.
Pole magnetyczne – stan przestrzeni, w której siły działają na poruszające się ładunki elektryczne, a także na ciała mające moment magnetyczny niezależnie od ich ruchu. Pole magnetyczne, obok pola elektrycznego, jest przejawem pola elektromagnetycznego [1].
2 lut 2022 · Magnets, or the magnetic fields created by moving electric charges, can attract or repel other magnets, and change the motion of other charged particles.
Learn how to define and visualize magnetic fields using compasses and field lines. Explore the properties and rules of magnetic field lines for bar magnets, current loops, and straight wires.
