https://en.wikipedia.org/wiki/ElectromagnetismElectromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles. The electromagnetic force is carried by electromagnetic fields composed of electric fields and magnetic fields, and it is

Xem thêmThe electromagnetic force is one of the four known fundamental forces. The other fundamental forces are:
• the strong nuclear force, which binds quarks to form nucleons, and binds nucleons to form nuclei.
• the weak nuclear force,...
Xem thêmIn 1600, William Gilbert proposed, in his De Magnete, that electricity and magnetism, while both capable of causing attraction and repulsion of objects, were distinct effects. Mariners had

https://simple.wikipedia.org/wiki/Electromagnetism- The electromagnetic force comes from something called an electromagnetic field. In physics, a field is how we keep track of things that might change in space and time. It is like a set of labels for every point in space. For instance, the air temperature in a room could be described by a field, where the labels are just numbers saying how hot it is at that point in the room. We could have …

Electromagnet - Wikipedia
https://en.wikipedia.org/wiki/ElectromagnetAn electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil. The magnetic field disappears when the current is turned off. The wire turns are often wound around a magnetic corem…

https://simple.wikipedia.org/wiki/ElectromagnetElectromagnets are temporary and artificial magnets. They are magnets that are only magnetic when there is a coil of wire with electricity running through it. The coil of wire is called a solenoid.The strength of the magnet is proportional to the current flowing in the circuit.The electricity running through the wire is called a current.

Électromagnétisme — Wikipédia
https://fr.wikipedia.org/wiki/Électromagnétisme- Pendant longtemps les phénomènes électriques et les phénomènes magnétiques ont été considérés comme indépendants[1]. En 1600, William Gilbert explicite, dans son ouvrage De Magnete, la distinction entre corps électriques (il introduit ce terme) et magnétiques. Il assimile la Terre à un aimant, note les répulsions et attractions des aimants par leurs pôles et l'influence d…

https://engineering.fandom.com/wiki/Electromagnetism- Electromagnetism is the physics of the electromagnetic field: a field, encompassing all of space, which exerts a force on those particles that possess a property known as electric charge, and is in turn affected by the presence and motion of such particles. The term electrodynamics is sometimes used to refer to the combination of electromagnetism with mechanics, and deals wit…
