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
Magnetism - Wikipedia Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic
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
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
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
What Are Magnets Made Of? | Magnet Basics When an atom – such as iron – has an odd number of electrons, those unpaired electrons create a magnetic field, turning the entire atom into a tiny magnet When most atoms in an object are tiny magnets, it produces an overall magnetic field with a north and south pole
