Magnet - Wikipedia A magnet is a material or object that produces a magnetic field This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc and attracts or repels other magnets
Magnetism | Definition, Examples, Physics, Facts | Britannica Magnetism, phenomenon associated with magnetic fields, which arise from the motion of electric charges It can be an electric current in a conductor or charged particles moving through space, or it can be the motion of an electron in an atomic orbital Learn more about magnetism in this article
How Do Magnets Work? The Physics Behind Magnetism At its core, magnetism is a force—a special kind of interaction between objects that can cause attraction or repulsion without physical contact Magnets produce magnetic fields, invisible regions of influence that can exert forces on other magnets or magnetic materials
What Is a Magnetic Material and How Does It Work? A magnetic material is any substance that produces its own magnetic field, which allows it to exert a physical force, attracting or repelling other magnetic materials or moving electric charges Magnetism is a fundamental physical force, closely related to electricity The unique properties that allow certain materials to exhibit this force are rooted within their atomic and subatomic
The Physics Classroom Tutorial: Magnetic Fields and Electromagnetism . . . Just as electric charges have electric fields surrounding them, magnets have magnetic fields that surround them This page explores the important concept of the magnetic field and how magnetic field lines communicate its strength and direction
How Magnets Work | HowStuffWorks Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt The magnetic field's lines of force exit the magnet from its north pole and enter its south pole Permanent or hard magnets create their own magnetic field all the time
22: Magnetism - Physics LibreTexts Magnetism is a subject that includes the properties of magnets, the effect of the magnetic force on moving charges and currents, and the creation of magnetic fields by currents
Magnetism - National Geographic Society To become magnetized, another strongly magnetic substance must enter the magnetic field of an existing magnet The magnetic field is the area around a magnet that has magnetic force
