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.
A magnet is a material that attracts iron and produces a magnetic field outside itself. Learn about the types, characteristics and applications of magnets, as well as the theory of domain magnetization and hysteresis.
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 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.
5 lis 2019 · Magnetism arises from the electromagnetic force of a moving electric charge. A magnet has an invisible magnetic field surrounding it and two ends called poles. The north pole points toward Earth's north magnetic field. The south pole points toward the Earth's south magnetic field.
A magnet is an object that produces a magnetic field and attracts unlike poles and repels like poles. Learn about the properties, types, characteristics and uses of magnets with examples, videos and FAQs.
Any charged spinning object is a magnet. Technically they have a magnetic dipole moment (μ). In this case, a moment isn't a brief period of time, it's an archaic term for the product of a scalar quantity (the strength of two magnetic poles) and a vector quantity (the displacement from the south pole to the north pole).
