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
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
Magnetism - Math is Fun Fridge magnets, compass needles and some door fasteners are all examples of permanent magnets Their magnetism comes from the "spin" of electrons This isn't like the spinning of a basketball, but a special kind of built-in property that makes electrons act like tiny magnets
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
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
